idea update GitHub description

https://taskwarrior.org/tools/ uses name and description for scrapping. Recommend adding android and iOS as keywords. E.g. from:

Taskwarrior-inspired mobile todo app

To:

Taskwarrior-inspired mobile todo app for Android and iOS

I'm not really sure what to do about that. The issue on my end is basically deliberate. I was aware of the issue at the tools page, but preferred wherever I had put some concise description.

Maybe they could scrape for tags?
