chore(gitea): sync generated plugin.json manifests for the mcp config

bash scripts/sync-plugin-content.sh --all after wiring the real
gitea-mcp server into plugins/gitea/.mcp.json — plugin.json (claude
profile) picks up the inlined server block (env omitted, since these
are public generated manifests), the copilot profile's plugin.json
picks up the ".mcp.json" pointer form. Also normalizes a pre-existing
description-field escaping drift the generator fixes as a side effect.
