Add type check in CI, ignoring the result

[lloeki]

Ignoring results because typing is not yet complete: this is to set up the struts of type checking execution in CI.

Ha, failing with:

#<Errno::ENOENT: No such file or directory @ rb_sysopen - /home/runner/work/graft-rb/graft-rb/rbs_collection.lock.yaml>

[lloeki]

Not sure if we should do this or commit the lock file.

Interestingly enough that's the kind of thing that's not handled by the magic ruby/setup-ruby+bundler-cache GHA...

I feel like with we are committing to do perform check with a specific ruby version, it does not harm to have the rbs collection lockfile checked into git.

[lloeki]

Same thought. Most things in the collection are version independent (the 0 directory) so it's not really an issue right now.

Let's keep it this way and we'll see.
