[language-typescript] Use proper comment delimiters in TypeScript…

…when inside of a TS block within a TSX interpolation.

Some mixing of TS and TSX is too ambiguous for the “Toggle Line Comments” command, but in this case we've got a brace-delimited block inside of a TSX interpolation. That's practically guaranteed to mean we've got a line with _only_ TypeScript on it, so we should use an ordinary TS line comment.
