tools.func: encode GitHub tag, refine pin logic, add Codeberg (#14473)

* Encode GitHub tag, refine pin logic, add Codeberg

Encode pinned GitHub tag slashes for API requests and avoid stripping a leading 'v' unless followed by a digit. Refactor pinned-version handling to match clean tags to raw tags, report missing pins, and set CHECK_UPDATE_RELEASE/messages appropriately. Add a new check_for_codeberg_release function to query Codeberg releases (uses jq, DNS check, handles legacy migration, pinned/latest comparison) so updates can be detected from Codeberg-hosted repos.

* Update tools.func
