chore(CI): fix CI

[rishav-karanjit]

Issue #, if available:

Description of changes:

• Issue 1: Retired macos-13:
  • Used macos-latest
• Issue 2: Python <3.11 incompatible with macOS latest runner
  • Excluded macos latest when python<3.11
  • TODO: use different runner when on python 3.11
• Issue 3: pytest using outdated Python ast module until pytest 7.3.1
  • This has been fixed on pytest>7.3.1 by [Python 3.12] Assertion rewriting triggers DeprecationWarning pytest-dev/pytest#10977
  • Moved out pytest deps to use 7.4.0 instead of 7.2.1 but see issue 4.
• Issue 4: Warning about pytest.warns(None) being deprecated on 7.4.0. In pytest 8+, passing None to pytest.warns() will be completely removed.
  • So, decided to move pytest deps to use 8.0.0 and migrate pytest.warns(None)
  • Note that I did not move the deps to use 9.x which is latest as it requires Python >=3.10 but we still support Python < 3.10 and have to test against it.
• Issue 5: -rc flag removed in isort command
  • rc flag is not required anymore, recursive is used by default without the flag.
  • See Missing '--recursive or -rc' flag in the new release. PyCQA/isort#1263
