We already have these earlier in the dict:

        '.3gp'    : 'audio/3gpp',
...
        '.3g2'    : 'audio/3gpp2',

So these new video ones overwrite the audio ones.

Should we change it to the video ones, and remove the audio?

Well, they're both official MIME types: iana.org/assignments/media-types/audio/3gpp and iana.org/assignments/media-types/video/3gpp. The only major difference as far as I can tell is that the former cannot contain any visual data

Interestingly, per the official 3GPP TS 26.244 V19.1.0 Specification:

The type "video/3gpp" is valid for all files. It is valid to serve an audio-only file as "video/3gpp".
