Deprecation warning when installing in editable mode

[lbianchi-lbl]

  DEPRECATION: Legacy editable install of idaes-pse[coolprop,dmf,grid,omlt,ui]==2.6.0.dev0
from file:///home/ludo/lbl/idaes/idaes-pse (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.

My guess is that is not something that's necessarily very urgent to address, but we should probably take this opportunity to start working on the switch to pyproject.toml.
