Optimize CI Pipeline

[SoulKa]

Is your feature request related to a problem? Please describe.
Inmost cases, The CI pipeline takes longer than it needs, since it runs npm run package which tests if the code is buildable.

Describe the solution you'd like
In my opinion, it's enough to test if the application is buildable if any dependency changed (package.json or package-lock.json was modified). If they are unchange in a PR, the npm run package step should be skipped.

What else could be changed
Please check if it makes sense to add an automerge to the dependerbot.
