chore(ci): bump prague to stable and osaka to develop

[spencer-tb]

🗒️ Description

Bumps Prague to stable and Osaka to develop in our CI.

Allows us to create an Osaka full release after merging this where fixtures_stable would contain Prague and fixtures_develop up to Osaka (refill-ing all our existing tests).

Actually requires #1508 if we want to wait for the last Prague-as-develop release.

Looks good overall, just a couple of requests:

• We need to remove the is_deployed method from Prague in src/ethereum_test_forks/forks/forks.py.
• This is a breaking change in the changelog.

[marioevz]

Made the fixes for this, but some unit tests are failing, particularly the src/cli/gentest/tests/test_cli.py unit tests are failing in Prague due to the branch currently being used, which fails to fill if the environment's block number is not 1.

@marioevz @spencer-tb I think we need to get this merged, cf #1856. It's going to make our ci v slow 😢

I just rebased on main, I think we'll have some tests to fix.

Looking at just now!
