Pull request overview

Updates Go module dependencies across the root module and the caddy/ submodule to keep indirect dependencies current and in sync with regenerated go.sum entries.

Changes:

• Bump github.com/pelletier/go-toml/v2 to v2.3.0 in both root and caddy/ modules.
• Bump several caddy/ indirect deps (notably cloud.google.com/go/auth, github.com/googleapis/gax-go/v2, github.com/yuin/goldmark, google.golang.org/api, and google.golang.org/genproto).
• Regenerate go.sum and caddy/go.sum to reflect the updated versions/hashes.
