TODO: Remove t.jSX* and t.tS* builders aliases

[nicolo-ribaudo]

EDIT: make this change on the final release.

#6967 makes the jsx and ts prefixes in node builders lowercase (e.g. t.jsxExpression() instead of t.jSXExpression()).

We can remove the old t.jSX* and *.tS builders. It is a breaking change, but

1. t.tS* aren't used yet by third party plugins because it has never been in a stable release
2. There aren't many plugins which build JSX nodes (actually, the only one I could find uses t.JSXIdentifier, so it would't be influenced by this change).
