feat(font): add commit-mono

[alexanderl19]

Adds Commit Mono v1.143 / v143.

Notes

Font files downloaded with default "customizations" from https://commitmono.com/ > 07 Customize then converted from otf to woff and woff2.

metadata.json

license url is set to the GitHub tag link (https://github.com/eigilnikolajsen/commit-mono/blob/v1.143/src/txt/license.txt), not commit (https://github.com/eigilnikolajsen/commit-mono/blob/a042aaa2a43da91544b1d02ee12819cb698db7d2/src/txt/license.txt). Should this be changed?

I've also selected to use the GitHub tag version of the font (v1.143) rather than the site version (v143). Not sure which one is preferable here.

{"weight":400,"italic":false,"alternates":{"cv01":false,"cv02":false,"cv03":false,"cv04":false,"cv05":false,"cv06":false,"cv07":false,"cv08":false,"cv09":false,"cv10":false,"cv11":false},"features":{"ss01":false,"ss02":false,"ss03":true,"ss04":true,"ss05":true},"letterSpacing":0,"lineHeight":1}

Conversion

Downloaded fonts are otf files. The following tools were used for conversion.

otf to woff: sfnt2woff-zopfli downloaded via bramstein/webfonttools tap (v1.1.0)

otf to woff2: woff2 via brew (v1.0.2)

Both using default settings.

Variable Font

Commit Mono is a variable font. I couldn't find any guidance on providing variable font files for non Google Font fonts. I'd like to be able to contribute those as well since they support OpenType features.

Edit: Just saw fontsource/fontsource#728.

Apologies for the delay. I was on holiday. 🎉

Everything looks good to me, except for the weights that are split at intervals of 25. This can be problematic if this font is ever uploaded to Google Fonts, as they will produce static variants with weight intervals of 100. In the long run, that could lead to a breaking change in a patch release due to how our system is set up (which automatically transitions to Google Fonts when available).

Could you remove the extra weights and only keep them in intervals of 100?
