[how-to-docs]: Add steps for installation of completion scripts by saehejkang · Pull Request #799 · apple/container

@saehejkang Could you rework this commit so that your changes are rebased onto the head of main, instead of merging main into the head of your branch?

Probably something like this on your local copy of your fork:

Get the latest apple/container main:

git checkout main
git fetch upstream
git merge upstream/main

Get rid of the merge commits in your feature branch, and sanity check your log to make sure you see the just your 791e092 and c46212c commits :

git checkout how-to-documentation-for-shell-auto-complete
git reset --hard c46212c
git log

Rebase your changes, and fix any merge conflicts you encounter, and then do a last sanity check to see that your diffs against main make sense:

git rebase main
git diff main

Once you're sure your local commit history looks good, rewrite your remote feature branch with the rebased commits:
