The experimental functions in `golang.org/x/exp/slices` are now
available in the standard library since Go 1.21.

Migrates us to `coder/websocket` v1.8.12 rather than `nhooyr/websocket` on an older version.
Works around https://github.com/coder/websocket/issues/504 by adding an explicit test for `xerrors.Is(err, io.EOF)` where we were previously getting `io.EOF` from the netConn.
re: #13327
Adds local interfaces to `coder netcheck` and checks their MTUs for potential problems.
This is mostly relevant for end-user systems where VPNs are common. We _could_ also add it to coderd healthcheck, but until I see coderd connecting to workspaces over a VPN in the wild, I don't think its worth the UX effort.
Netcheck results get the following:
```
"interfaces": {
"error": null,
"severity": "ok",
"warnings": null,
"dismissed": false,
"interfaces": [
{
"name": "lo0",
"mtu": 16384,
"addresses": [
"127.0.0.1/8",
"::1/128",
"fe80::1/64"
]
},
{
"name": "en8",
"mtu": 1500,
"addresses": [
"192.168.50.217/24",
"fe80::c13:1a92:3fa5:dd7e/64"
]
}
]
}
```
_Technically_ not back compatible if anyone is parsing `coder netcheck` output as JSON, since the original output is now under `"derp"` in the output.
Adds checks to coderd/healthcheck/derphealth for STUN issues:
- Alerts if there is not least one healthy STUN server,
- Alerts if we see variable port mapping.
Currently, importing `codersdk` just to interact with the API requires
importing tailscale, which causes builds to fail unless manually using
our fork.
Moves healthcheck report-related structs from coderd/healthcheck to codersdk
This prevents an import cycle when adding a codersdk.Client method to hit /api/v2/debug/health.
* Force typegen types for some fields of derp health report
* Explicitly allocate slices for RegionReport.{Errors,Warnings} to avoid nulls in API response
Relates to #8965
- Added error codes for separate code paths in health checks
- Prefixed errors and warnings with error code prefixes
- Added a docs page with details on each code, cause and solution

* Adds workspace proxy section to health page
* Conditionally places workspace proxy warnings in errors or warnings based on calculated severity
* Adds some more stories we were missing for HealthPage
Adds a health check for workspace proxies:
- Healthy iff all proxies are healthy and the same version,
- Warning if some proxies are unhealthy,
- Error if all proxies are unhealthy, or do not all have the same version.
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
