Translate the README into Amharic (አማርኛ) #35

gknowledge works offline and without a paid API key, which makes it useful where data is expensive or connectivity is patchy. A README in Amharic (አማርኛ) would help readers in Ethiopia discover it.

Task

1. Copy README.fr.md or README.es.md (the short translated READMEs) to README.am.md, using the English README as the source text.
2. Translate the prose. Keep commands, code blocks, links and badges unchanged.
3. Add <a href="README.am.md">አማርኛ</a> to the language bar at the top of every README*.md.

Please write it yourself as a native or fluent speaker: machine-translated PRs will be asked for revisions. Comment here to claim the issue.
