My last edits about grep tool

Hello, I apologize for my latest contributions about https://grep.toolforge.org/ messages on translatewiki.net. I wanted to translate messages into my language, but I don't know why I edited the English messages. Anyway, I've added them to my language now. Thank you!

No worries! :) It's not actually that uncommon for other languages to get into en-gb, I'm not sure why! Possibly there's some off-by-one menu selection or something.
