Explain possible values for the font-style configuration

[borasemiz]

The font-style configuration, in my opinion, should explain the possible values it accepts and how. After reading the section, what I understood is that this field accepts official font weight names, such as: "Thin", "Medium", "SemiBold" or "Bold". The explanation of this config gives no suggestion about the possible values therefore I have to do trial and error if my assumption works. It would be extremely reader friendly to explain all the values that this field accepts, and in what way (eg case sensitive or not). Yes, I can take a look at the source code, but hey, I don't want to.

I mean, the way it's phrased is a bit awkward, but it does state that it requires a named style advertised by the font itself, along with an example:

The named font style to use for each of the requested terminal font styles. This looks up the style based on the font style string advertised by the font itself. For example, "Iosevka Heavy" has a style of "Heavy".

Feel free to open a PR to rephrase this in the way that it makes sense to you (config docs are in src/config/Config.zig) but to me it's unambiguous enough.
