webRequestBlocking for Manifest V3

Extension Manifest V3 might have made webRequestBlocking a pain in the ass to migrate, but it isn't impossible to use.

How to use this

1. Fork or clone the repo
2. Go to /Extension/src/block.json
3. In line 9, change example.com to the domain you want to block.
4. Finally, npm run build at /Extension/.
5. Done! You now have a blocking extension in .zip, .xpi, and .crx format.
6. Remember, if you're using this as production software, remember to sign the .CRX file (Go to chrome://extensions, enable Developer Mode, and use Pack Extension).

How this is done:

Using MV3 declarativeNetRequest rules, we can block requests.
