to change the changelog, write text/changelog_en.json in following format:

[
    {
    "icon": "the name of icon for the changelog item, must be present in icons/, do NOT include .svg",
    "title": "title of item",
    "description": "description of item"
    }

]

all 3 elements are optional, ui will just omit them if you don't provide them.

after you write it, run "dart run tool/translate_changelog.dart" to fill in the rest of the languages
