Add codespell gh workflow

[eapolinario]

Why are the changes needed?

Typos make the project look unprofessional, so in the same vein as flyteorg/flyte#5418.

What changes were proposed in this pull request?

We added a new gh workflow that only runs the codespell utility as flyteorg/flyte#5418.

I also removed dev-requirements.txt opportunistically, since it's not really used in the repo anywhere.

How was this patch tested?

Ran make spellcheck

Can we make this a precommit hook, so that make lint catches these issue before we push?

Usinga a pre-commit-hook means we can keep the config in pyproject.toml.

Good call. This is already a precommit hook. I'm updating the version (and fixing a few typos) in #2630.
