Remove pattern MLS entries (#2371)

## Description:

Since pattern data is now dynamically fetched from the server,
maintaining direct translations here is no longer meaningful.
This change removes those entries and also helps prevent exceeding the
Crowdin string quota.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
