## Description
This PR adds a warning to the prebuilds documentation about
incompatibility with Workspace schedule (autostart/autostop), dormancy,
and DevContainers. These configurations can interfere with prebuild
behavior and should be avoided for now.
Preview:

As part of an information architecture overhaul, this PR reorganizes the
About section and adds a Support section (but not content to it yet)
[preview](https://coder.com/docs/@docs-ia-about/about)
this PR is intentionally limited in scope so that we can ship meaningful
changes faster and followup PRs should include:
- [ ] edit + overhaul the About page
- [ ] decide on the `start` directory
- [ ] ~screenshots page updates~ (this should happen July or later)

## Summary
This PR introduces support for expiration policies in prebuilds. The TTL
(time-to-live) is retrieved from the Terraform configuration
([terraform-provider-coder
PR](https://github.com/coder/terraform-provider-coder/pull/404)):
```
prebuilds = {
instances = 2
expiration_policy {
ttl = 86400
}
}
```
**Note**: Since there is no need for precise TTL enforcement down to the
second, in this implementation expired prebuilds are handled in a single
reconciliation cycle: they are deleted, and new instances are created
only if needed to match the desired count.
## Changes
* The outcome of a reconciliation cycle is now expressed as a slice of
reconciliation actions, instead of a single aggregated action.
* Adjusted reconciliation logic to delete expired prebuilds and
guarantee that the number of desired instances is correct.
* Updated relevant data structures and methods to support expiration
policies parameters.
* Added documentation to `Prebuilt workspaces` page
* Update `terraform-provider-coder` to version 2.5.0:
https://github.com/coder/terraform-provider-coder/releases/tag/v2.5.0
Depends on: https://github.com/coder/terraform-provider-coder/pull/404
Fixes: https://github.com/coder/coder/issues/17916
We probably shouldn't be suggesting `ignore_changes = all`. Only the
attributes which cause drift in prebuilds should be ignored; everything
else can behave as normal.

These items came up in an internal "bug bash" session yesterday.
@EdwardAngert note: I've reverted to the "transparent" phrasing; the
current docs confused a couple folks yesterday, and I feel that
"transparent" is clearly understood in this context.

Closes https://github.com/coder/internal/issues/369
We can't know whether a replacement (i.e. drift of terraform state
leading to a resource needing to be deleted/recreated) will take place
apriori; we can only detect it at `plan` time, because the provider
decides whether a resource must be replaced and it cannot be inferred
through static analysis of the template.
**This is likely to be the most common gotcha with using prebuilds,
since it requires a slight template modification to use prebuilds
effectively**, so let's head this off before it's an issue for
customers.
Drift details will now be logged in the workspace build logs:

Plus a notification will be sent to template admins when this situation
arises:

A new metric - `coderd_prebuilt_workspaces_resource_replacements_total`
- will also increment each time a workspace encounters replacements.
We only track _that_ a resource replacement occurred, not how many. Just
one is enough to ruin a prebuild, but we can't know apriori which
replacement would cause this.
For example, say we have 2 replacements: a `docker_container` and a
`null_resource`; we don't know which one might
cause an issue (or indeed if either would), so we just track the
replacement.

2. The 'populate recently used parameters' feature still requires the
auto-fill-parameters experiment flag

This PR changes template names and docs to follow the
`<provider>-<os/whatever>` format for all templates.
I've decided not to split this into multiple PRs because I'd have to
edit rebase the other PRs once one of them gets merged, this should be
relatively low-impact anyways.
This aligns with our goals to make templates more user-friendly.
Closes#15754
- Adds documentation for how to correctly hold --parameter with list(string)
- Adds tests for the aforementioned documented correct finger positions for --parameter list(string)
