Unable to upload .py files from google chrome with the default supportedMimeTypes config

[s1sfa]

What happened?

It looks like some browsers send different types for python files. Google chrome sends text/x-python-script, resulting in error.

I supposed it's configurable to add this to the yaml config, but it seems like the intention is to enable python files by default because, text/x-python seems to be accepted with the same default config.

Is this an update you would be willing to make for future versions so all browsers can upload .py files?

Steps to Reproduce

This shouldn't be an issue on latest, which is now at tag v0.8.2-rc2

I was looking at the code https://github.com/Gerald-M/LibreChat/blob/4a2de417b68dd5948e06bf71c939462405ad46c1/packages/data-provider/src/file-config.ts#L42-L43 I don't think it will match x-python-script which is what chrome sent. FWIW I tested this in FireFox 146.0.1 and it also gets sent as text/x-python-script
