Remove "uuid" dependency (#3811)

## Description:

One dependency less: remove uuid. It is only used to get the three
random digits after "Anon" if no name is present in localStorage.
Crypto.randomUUID also gives us a UUID v4 and can already be used from
Utils > generateCryptoRandomUUID. Not noticable when it comes to speed
either.

## 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:
