chore: improve GH workflows

[lisabaut]

Description

This PR improves the current workflow set-up as such:

• include the script yarn lint
• make iOS workflow a re-usable workflow (=> see the docs for more information)
• make android workflow a re-usable workflow
• read the node version from the nvmrc file
• pass this node version to all workflow jobs

Re-usable workflows need to be addressed directly with the correct path (tag, commit-hash, branch name)
In order to prove that everything is working I needed to point the workflows to this branch of this PR.

See the succesfull Working Workflow here (which points to this branch to avoid errors)
https://github.com/react-native-mapbox-gl/maps/actions/runs/1367197447

The next commits in this PR will replace the path again to master in order to make the actions run successfully when merged to master.
But this led to failing actions on this PR again of course. Just to let you know that this was expected. (=> failing action run)

In general, one can go more wild now with the extracted and re-usable workflows, like for example:

• extract the publish job and create a dedicated workflow file for releases and re-use the iOS and Android workflow
• do some other actions when a PR was opened and re-use the workflows again
• other ideas

Checklist

• I have tested this on a device/simulator for each compatible OS
• I formatted JS and TS files with yarn lint
• I updated the documentation yarn generate
• I mentioned this change in CHANGELOG.md
• I updated the typings files (index.d.ts)
• I added/ updated a sample (/example)
