Work started on feat/abs-1416
https://smg-re.atlassian.net/browse/ABS-1416

Various improvements :

In order for new branch to be created based on the latest version of main, we need to run 2 commands before git checkout - b BranchName

One way of doing this is to run :

git checkout main
git pull

We also allow empty commit :
git commit --allow-empty -m "chore: initialize ${BRANCH_NAME}"

We verify for uncommitted staged changes, and inform what would happen to those :

if ! git diff --cached --quiet; then \
    echo "You have uncommitted staged changes. By continuing this will include those changes in the first commit of the new branch and PR."; \
...

We have 2 issues
not All repos have "main" as default branch.
Making my git checkout main not working in case of "master" as default.

this command is also going to fail if default branch is not "main".
gh pr create --repo "$REPO" --title "${BRANCH_NAME}${PR_TITLE}" --body "Work started on $BRANCH_NAME" --base main --draft; \
with error
pull request create failed: GraphQL: Head sha can't be blank, Base sha can't be blank, No commits between main and feat/ABS-1417, Base ref must be a branch (createPullRequest)

We could verify if default branch is main or master, before applying the commands ?

@gergo-dryrun
Though this version includes all changes we have talked about, the test file doesn't work.
But it also doesn't work with the main branch anymore either it seems.
3/4 tests are constantly failing for me.

We can get back to this when I am back from holiday on the week of 11th February.
