I believe "application/font-off" is a typo for "application/font-otf"

I have tried my best, but I have been unable to find a single reference to the mime type "application/font-off", either in the referenced RFC 8081, iana, any rfcs, or stackoverflow:

1. iana: https://duckduckgo.com/?q=site%3Aiana.org+%22application%2Ffont-off%22&ia=web
2. rfcs: https://duckduckgo.com/?q=site%3Arfc-editor.org+%22application%2Ffont-off%22&ia=web
3. stackoverflow: https://duckduckgo.com/?q=site%3Astackoverflow.com+%22application%2Ffont-off%22&ia=web

I have however found plenty of mentions of "application/font-otf", which does not appear in this document. The first occurrence of "application/font-off" seems to be in this commit. There doesn't appear to be much provenance there, but I imagine it was simply a typo at the time. If we agree, can we change this to "application/font-otf"?

Looks like this typo made it into Web Platform Tests too.

I suspect this never surfaced due to #60.

That JSON file in WPT is not actually used by any WPT test.

If someone writes a PR fixing just this issue I think that would be okay though, but the larger question is whether we need this list at all. Or at least whether we need it within the web platform.
