Bumping `github.com/golang-jwt/jwt` from v4 to v5. `github.com/golang-jwt/jwt` v5 is bringing some breaking changes: - standard `Valid()` method on claims is removed. It's replaced by `ClaimsValidator` interface implementing `Validator()` method instead, which is called after standard validation. Gitea doesn't seem to be using this logic. - `jwt.Token` has a field `Valid`, so it's checked in `ParseToken` function in `services/auth/source/oauth2/token.go` --------- Co-authored-by: Giteabot <teabot@gitea.io>
