Update Manifest version from v2 to v3

Similar issue for another extension: ClearURLs/Addon#326

We'll do that as late as possible. In short: MV3 sucks.

Migrating to MV3 gains nothing, requires the user to do more configuration for normal functionality, and may introduce issues (since the service worker may be randomly killed and requires a restart when needed, it may cause some network requests not correctly blocked).

We already have the MV3 beta version, whose link is visible in the description of the Chrome Web Store. Test it if you're interested in.

Agree MV3 sucks
But way too many Chromium browsers in the field (and also Firefox sucks in its own way to get enough people using it lol)
I will test beta version when free thanks ;)

As CleanURLs won't work with Chrome MV3, I've created a comparable extension using the MV3 framework. I invite you to join our project at Linkumori on GitHub. https://github.com/subham8907/Linkumori

MV3 version so far so good
Sad to see MV2 goes for many browsers but grateful to have something left for those browsers
Using Zen Browser (a Firefox fork) but many things are still unstable to become my main browser (using Vivaldi
Thanks for working on this ~
