feat: allow custom role attribute on Table component

[blaky]

This PR adds an optional role prop to the Table component to allow other kind of role values such as treegrid.
I had to update the yarn.lock file as it was referring to NPM registries that no longer exist.

Hi @bvaughn

I would appreciate if you could review this pull request.

Many thanks in advance!

Sorry for the very long delay in getting back to you about this!

I've just finished a large update for version 10 of react-virtualized (#1900): the library has been rewritten in TypeScript, every component is now a function component (React 18+ is required), and the source moved from source/ to lib/. Because of that, this PR can't be merged as-is. Version 10's Table still hard-codes role="grid".

If you're still interested in this change, I'd welcome a new PR with it rebased onto the version-10 branch (or onto master once version 10 has been merged).
