Some suggestions:

• after applying yq, check if there is a diff. If not, create an output to indicate so and only run subsequent tasks if the output is true.

  if [ "$(git status --porcelain=v1 | wc -l)" > 0 ]; then
      echo "has_diff=true" >> $GITHUB_OUTPUT
  else
      echo "has_diff=false" >> $GITHUB_OUTPUT
  fi

• Check if the pr already exists. If so, don't create but edit. Also reset the branch to the origin dev and add a fresh commit, removing the old commit.
• Alternatively, create a PR on release, using GITHUB_REF to determine which chart to update. Each chart can have its own PR. This is more like dependabot.

@keyvaann @pvannierop Can we revive this idea? How much work is left on this?
