Auto update

[asbjornu]

Implement auto-update. Resolves #47. Still a draft as I'm inching my way forward. Current status:

• Installation of NPM packages via package.json.
• Auto-update of NPM packages via package-lock.json.
• Installation of APK packages via apk.json.
• Auto-update of APK packages via apk.json.

I went for the separate package file solution since I think that's a cleaner and more maintainable approach than providing custom regex configuration for Renovate. The PR currently fails the runner / markdown-lint (github-pr-review) workflow due to the following command:

reviewdog -f=remark-lint -name=remark-lint -reporter=github-pr-review -filter-mode=added -fail-on-error=false -level=error -tee '-filter-mode=file -fail-on-error'

producing the following error:

invalid value "file -fail-on-error" for flag -filter-mode: invalid mode name: file -fail-on-error

I don't really understand why, so any pointers would be very helpful.

@asbjornu Thanks for the work you have done. I am a bit short on time this month, but I will investigate the error when I find some time.

It looks like migrating to a composite action #57 solves the errors that were thrown. @asbjornu Can you check if your other problems are also solved?

@asbjornu If you still planning to implement this feature, I think it now works better on v5.0.0.
