It would probably a good idea to also make an addition to the readme so users are aware of the newly added command. and it might be probably also helpful to add a brief note about how and more importantly when to use that command. i was for example completely unaware of the existence of that script and ive simply tried running ddev exec core/scripts/dev/commit-code-check.sh and got There are no files to check. If you have staged a commit use the --cached option. in return. so i assume the script should only be executed on a checked out MR with uncommitted files?

Good idea :) I added some instructions and other small fixes.
