Call for helpful examples that are small in scope

[rpearce]

There are a number of different examples in https://github.com/rpearce/bashcards/tree/main/examples, but some especially useful additions might be to:

• add more helpful bashcard practice lines to any of the existing *.bcrds files (the maths.bcrds one could use more!)
• add a functional programming jargon file that has concise yet helpful practice cards
• add a language file for your favorite language that isn't already in there
