[Enhancement]: Support uploading .h files

[jasongilman]

What features would you like to see added?

If you try to upload a .h file, as associated with C and C++, the UI displays an error "Unable to determine file type for: file_name.h"

More details

I think this would just be a change to add it here in file-config.ts

Which components are impacted by your request?

This was pretty straightforward. Raised a PR to get this added.

PR is merged and it should be closed once this goes to main.
