Add test for queries

[s-weigand]

Since the recent changes in the GitHub websites markup broke this extension again (thx for the quick fix ❤️), IMHO it is a good idea to test for changes in the supported page's markup on schedule (i.e. daily).

The changes introduced by this PR are:

• Added query tests for all supported pages, except PasteBin (couldn't find an example that fits)

• Fixed problem with breadcrubs on GitHub when in a folder

  • Before:
    
  • After:
    

• Fixed problems with BitBucket (selector + update event)

• Activated SourceForge by default and added right margin for the icons

  • Before:
    
  • After:
    

• Replaced travis CI with github actions (example CI output)

• Made tests automatically upload build extensions
  

The tests for GitLab and BitBucket are run using puppeteer, because the page is rendered by javascript and the queried elements aren't present if the page is only fetched.

Wooow, I see plenty of improvements here... 👍
Everything looks great :) ! My only question is if its possible to automatically build artifcat (npm run build:prod) when I push tagged branch to git (for example rc-1.23) ?

Atm the CI it builds the artifacts on push, PR and on schedule (tag is also counted as push as far as I know).
But there are also actions to publish extensions for chrome and firefox (not sure about opera), which you can setup to do so on tags.
I publish my extension on tag push cia the CI.
If you want I can add a seperate workflow for publishing on tag push, the guide on how to get all API keys can be found here.
