pallet projects get type hints: Click, Werkzeug, MarkupSafe, ItsDangerous, Flask, Jinja

[Akuli]

I asked on pallets projects discord:

The next versions of all 6 projects will be released in a few weeks, and they'll all be fully typed and provide the py.typed marker. Click, Werkzeug, MarkupSafe, ItsDangerous, and Flask are done already, and I'm working on Jinja right now.

I was going to open an issue in typeshed notifying about this once they were released. It's my understanding that py.typed will be preferred over typeshed, and typeshed will drop support after 6-12 months.

For now, should we keep accepting pull requests for these projects or just tell people to wait?

It's fine to accept PRs still.
