Having issues Using Python311

[lost-rob0t]

I was Planning on using mach-nix for my project but i found out that i am not able to use Python311, which i assume is because of this line
lib.supportedPythonVersions = [ "27" "36" "37" "38" "39" "310" ];
Im not entirely sure how to work with this large repo locally as git on my end is not liking it.

 git commit -m "Added Python 3.11"

Error Message in question

error: The pypiDataRev seems to be older than the nixpkgs which is currently used.
       Because of this, mach-nix might lack dependency information for some python packages in nixpkgs.
       This can degrade the quality of the generated environment or result in failing builds.
       It is recommended to pass a newer pypiDataRev to mach-nix during import.
       For flakes users: Update the `pypi-deps-db` input of mach-nix.
       You can ignore this error by passing 'ignoreDataOutdated = true' to mk* or build* functions
