📌 Summary

Several of the automated PRs created by the CI action change little or nothing about the generated manifests. The utility script bin/compare.sh shows the differences, and the reviewer can merge such small patches without testing if there are no differences shown.

The workflow is executed on every PR that has the label chart-deps, and re-run on every commit except for merge commits.

This PR also includes some fixes and tweaks for the bin/compare.sh script:

• Quoting arguments
• Fixing the output path of Helmfile
• Adding a --diff-output argument to specifically extract that part of the result and attach it to the PR. The entire output can still be seen in the job log, if needed.
• Save the script directory in a variable. This way, bin/compare.sh and bin/dyff.sh can be copied to a different location for the purpose of testing, as running them changes the current branch.
• Calling the otomi.ts script directly with node, as using the bash script has caused issues.
• Skipping hooks on changing branches, as this has further dependencies (e.g. nvm) which are not relevant for the comparison.
