test: reduce date and version noise in AboutFragment test

[BrayanDSO]

Purpose / Description

The date in AboutFragment changes when a commit is done on a new day, which generates noise on its screenshot test. Same for new versions

#21075 (comment)

Note

The version of Anki's backend and FSRS may generate diffs as well, but upgrading them is a rare event, so I kept the diff as an extra "confirmation" after doing the upgrades

How Has This Been Tested?

./gradlew :AnkiDroid:recordRoborazziPlayDebug -Pscreenshot --tests "com.ichi2.anki.preferences.*"
