Dear Maintainer,

`file -i archive.rar` currently reports a MIME type of: application/x-rar

However, according to sources like https://www.iana.org/assignments/media-types/application/vnd.rar

the correct MIME type should be application/vnd.rar

and the deprecated MIME type was application/x-rar-compressed

It has never been application/x-rar as far as I can tell.

Dear Maintainer,

this has now led to actual breakage on one system, because `file`
outputs the MIME type differently to other tools.

For illustration:

```
$ python3 -c 'import mimetypes; print(mimetypes.guess_extension("application/x-rar-compressed"))'
None
```

```
$ python3 -c 'import mimetypes; print(mimetypes.guess_extension("application/x-rar"))'
None
```

```
$ python3 -c 'import mimetypes; print(mimetypes.guess_extension("application/vnd.rar"))'
.rar
```

```
$ python3 -c 'import mimetypes; mimetypes.init(); print(mimetypes.types_map[".rar"])'
application/vnd.rar
```

Please try to make `file` output the MIME type as application/vnd.rar in
time for debian trixie.

Thank you.
