chore: Bump Firefox outdated browser version

[Gudahtt]

Description

The outdated browser version for Firefox has been bumped to 102. Users on older versions of Firefox will now see a warning saying that their browser is outdated. This is inpreparation for updating our minimum supported Firefox version to 102.

102 is the previous ESR version, which matches our browser support policy (we support the current and previous ESR Firefox versions).

Tested this by setting my useragent in Firefox, the message pops up if it's lower than 102.
