Legacy editable install is deprecated

[CodeWithEmad]

Looks like as of pip 24.2, the legacy editable install is marked as deprecated. https://pip.pypa.io/en/stable/news/#v24-2

DEPRECATION: Legacy editable install of xblock-sdk==0.13.0 from file:///home/emad/xblock-sdk (from -r requirements/local.txt (line 4)) (setup.py develop) is deprecated.
pip 25.0 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64.
If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. 
Please consult the setuptools documentation for more information. Discussion can be found at https://github.com/pypa/pip/issues/11457

As it says, "A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64"

@feanil I'm unsure if this repo is the best place to mention this issue. Kindly let me know if it's in the right place (or if it's even a valid issue that we should work on).

@feanil I know you've mentioned that we need to migrate to pyproject.toml within the next couple releases. I'm adding this issue to the maintenance board so we can track that.
