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.
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 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
