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.
