component_guide: Update import-debian-package documentation
Task: https://phabricator.apertis.org/T8106
import-debian-package script now runs all the steps automatatically. The recently added --push-remote option allows creating and pushing the imported package to apertis remote gitlab instance.
The following steps are now automatized:
- package folder is created and import process is performed in there.
- remote repo is created if it doesn't exist.
- remote branches and tags are pushed.
- gitlab settings are applied to remote repo.
- CI pipeline is triggered on all downstream branches.
The previously manual steps (performed now by the script) are kept documented in the import-debian-package repository.
