Ruby: ignore more command history files

[blooper05]

Reasons for making this change:

Nowadays, with the advent of debug.rb and the active development of IRB, etc, the realistic options of debuggers and REPLs in the Ruby world have been expanding. So now, it would be very useful to add the command history files of these leading tools here 🙌
