allow install and link of both fc_bundle_py312 and fc_bundle_py312_qt6

[ipatch]

presently only of the formula can be linked due to the same variable / filename in the formula ie. freecad-py-modules.pth both formula use the same name for the file, thus the below error will be encountered,

╰─λ brew install fc_bundle_py312 -v                                                                                     0 (0.587s)

==> Finishing up
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /Users/chris/homebrew
Could not symlink lib/python3.12/site-packages/freecad-py-modules.pth
Target /Users/chris/homebrew/lib/python3.12/site-packages/freecad-py-modules.pth
is a symlink belonging to fc_bundle_py312_qt6. You can unlink it:
  brew unlink fc_bundle_py312_qt6

To force the link and overwrite all conflicting files:
  brew link --overwrite fc_bundle_py312

To list all files that would be deleted:
  brew link --overwrite fc_bundle_py312 --dry-run

Possible conflicting files are:
/Users/chris/homebrew/lib/python3.12/site-packages/freecad-py-modules.pth -> /Users/chris/homebrew/Cellar/fc_bundle_py312_qt6/0.9.2/lib/python3.12/site-packages/freecad-py-modules.pth
==> Caveats
    this formula is required to get necessary python runtime deps
    working with freecad
