Restore ProxyRequired to preserve the public API.

CefErrorCode is public, and LoadErrorEventArgs.ErrorCode exposes it to downstream applications. Removing ProxyRequired can cause existing source references to fail compilation. Retain ProxyRequired = -368 with [System.Obsolete], or document this intentional breaking change in the release and versioning metadata.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@CefSharp/Enums/CefErrorCode.cs` at line 1152, Restore the public
CefErrorCode.ProxyRequired member with value -368 and mark it System.Obsolete,
preserving existing LoadErrorEventArgs.ErrorCode consumers and enum
compatibility.

After applying the fix, consider running `coderabbit review --agent` for local
