Create target-branch if it doesn't exist

[melody-universe]

Quoted from issue #70:

I might be doing something wrong, but if I set the target-branch property, I get the following:

✖  fatal     Error: Command failed: git checkout development 
error: pathspec 'development' did not match any file(s) known to git.


    at makeError (/node_modules/execa/index.js:174:9)
    at /node_modules/execa/index.js:278:16
    at processTicksAndRejections (internal/process/task_queues.js:93:5)
    at async /index.js:99:5

Ideally, this action should try to fetch target-branch, and if it doesn't exist, create it.

+1 on this issue...

My dev branch has restrictions to merging and requires 1 PR. So the merge fails. But I also can't push to a target branch dynamically due to this issue.

I think ideally it should push to a new branch and open a PR.

Maybe you want to use skip-push: true https://github.com/phips28/gh-action-bump-version#skip-push (does not commit nor push any tags) and then create your own script to do what you need.
