What does this Pull Request (PR) do?

Update unpatched fonts for Iosevka to 5.0.3 + LICENSE + README

How should this be manually tested?

Any background context you can provide?

I got this when running the gotta-patch-em-all-font-patcher!.sh script

Failed to remove subtable: 'dlig' Discretionary Ligatures lookup 33 contextual 11

Also using the tested font patched with font-forge, I got glyph overflow (2 pixels size for 1 pixel icon) and don't know what is the cause.
I have no idea what to do with either config.cfg or config.json.

What are the relevant tickets (if any)?

#455

Screenshots (if appropriate or helpful)
