feat: display changelog modal on new version to improve awareness (#2403)

## Description:

Following discussion on discord, some people (including me) thought it
would be nice to show the changelog whenever there is a new version, as
people seemed not to be aware of the gameplay change

## 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
