AgileRL tutorial is broken again. I think I can fix that and I'll pin the version so it won't be an issue in the future

Tests are failing due to AgileRL version change. #1193 should resolve that.

Apparently the failure to train with SB3 wasn't a bug with the env, it was a SB3 tutorial bug. I removed the change that "fixed" the env because it was wrong. I believe the rest of the changes are valid, but I don't think it requires a version bump, so I moved it back to v3.
