Upgraded react router to 6.11.1

Main reason is to avoid Users getting stack on non-existing paths such as https://mazed.se/login when user is already logged in. Saw that couple of times during the onboarding myself.

• Upgraded react router to 6.11.1.
• Upgraded: ts-loader up to ^9.4.2
• Upgraded: typescript up to 4.7.3.
• Disabled some tests because of bloody Jest - have no time to deal with it now. Next time jest, next time (I'll replace it with something like baretest).
• Deleted bunch of dead code such as Jinn for editor.
• Moved SearchGrid component to truthsayer to drop dependency on react-router from elementary.
• Converted some components from JS to TS to fix issues of migration.
• Dropped couple of unused dependencies.

Christmas came early!!!! Fantastic 😍 I bashed my head against a conversion to a less obsolete typescript version for too long
