Provide lite version (text version)

[jelly]

Currently arch-wiki-lite isn't really maintained it seems, it would be cool if this script could also generate a plaintext version which saves a lot of space and doesn't require a browser per se.

I could probably easily generate a text-only version, but technically arch-wiki-lite is more than just a bunch of text files - it has at least a search engine and console viewer. I don't think that moving those scripts here would make them more maintained and if they continue to exist in a separate package, I probably wouldn't bother with making a text-only version either. After all, unless something is broken in arch-wiki-lite, it's just a matter of rebuilding arch-wiki-lite regularly (preferably along with arch-wiki-docs).
