🩹Fix broken deployment build (#246)

* 🩹 Downgraded size-plugin to 2.0.2 

since version 3.0.0 doesn't work with webpack 5.

Ref: GoogleChromeLabs/size-plugin#40 (comment)

* 🩹 Fixed 'npm run update_manifest_firefox' and added test to 'Test' workflow


Fixes the Error:
$ npm run update_manifest_firefox

> @ update_manifest_firefox /home/runner/work/binge-stream/binge-stream
> npx ts-node tools/firefox_manifest_append.ts

npx: installed 14 in 2.154s
