chore: rm old references to devnet fork; rm exec fork refs

[fselmo]

🗒️ Description

• feat(tooling): replace tox with just #709 caught and fixed some old references to --fork=devnet that were related to those changes. This PR aims to fix the remaining ones as they would've been out of context in that PR.
• Remove references along the way for Shanghai as some potential future execution fork as that is out of scope for now.

Will wait until #709 is merged to rebase here and make sure all the remaining references are caught then mark as ready for review. [done]

✅ Checklist

• Ran just checks to avoid unnecessary CI fails:

  just check

• Considered adding appropriate tests for the changes.
• Considered updating the online docs in the ./docs/ directory.

Thanks a lot @fselmo this is ready to merge no?

I found a few more after rebasing... should be good to review now.

One q I had is how to address tests/consensus/devnet? This is based on "devnet fork" as the __init__.py docstring mentions. Did you want to rename this dir to lstar? Leave this alone for now or?

Yes I think we can rename to lstar, do you want to group this into this PR?
