fonts: remove all desc stanzas

[miccal]

Since we do not require a desc stanza for fonts, and in the spirit of consistency, I propose we remove them all.

See #174976 for more context.

Note that there are currently 2,265 font Casks, and only these 585 currently have a desc stanza.

I would argue the opposite: for consistency all casks should have a description including fonts.

I don't really see a benefit in fonts not having one.

Descriptions aren't often useful for fonts would be my additional thought here.

"Geometric sans-serif font" - doesn't say much.
Outside of these kind of descriptions it's mainly marketing blah blah.

I don't know if it matters that some have descriptions and some don't though.

I'm fine with removing these for the reasons stated above.

Thank you @p-linnane.

Would like to make after-the-fact arguments for reverting this:

It feels much nicer to have descriptions on some fonts rather than none. If a description for a given font isn't useful: it does no harm. Removing, at least in my case, several useful descriptions feels like consistency for consistency's sake and does not make things better for users.

I would argue the opposite: for consistency all casks should have a description including fonts.

I don't really see a benefit in fonts not having one.

I agree with this. It'd be nice to reinstate these descriptions by reverting this PR, requiring descriptions on all new fonts and making a help wanted issue to add them to existing font casks.
