[3.15] Add tests for syntax error messages that had no test coverage (GH-153192) (GH-153196) Add tests for syntax error messages that had no test coverage (GH-153192) "illegal target for annotation" and "cannot use dict unpacking here" were not tested at all, and "f-string: expecting '!', or ':', or '}'" was only tested for its t-string variant.
