Adding support for React 18 :)

Adding incremental support for React 18.

Extremely sorry if I made any mistakes :(

Please see #7102 and #7264. We have agreed to put this off till v3, and we have multiple dependencies blocking this, so now is not the time yet. Thanks for taking interest in this, but as the PR template (which you deleted) asked, please file an issue and get the maintainers' approval before working on any non-trivial change.

The main problem is that MDX v1 declares the same peer dependency range as we currently do. So if you use a package manager that's strict about peer dependency versions, you can't install React 18 successfully anyway (because MDX v1 blocks it); if you use one that's permissive, you should be able to use React 18 currently as well (as I have personally tried with Yarn).

Nothing to be sorry about—feel free to comment under #7264 about what you are facing and what you think we should do :) AFAICT, users don't have any more or less difficulty migrating to React 18 regardless of what we do.
