add workflow tool: automate simple text changes

I observe that

Let's put this in a shell script so that it is transparent

I think it's all possible, except i am not sure about step 6 being done remotely as i have never done it

I think it could be called edit-text.sh or something, and should do the following:

1. Usage is edit-text im-gonna-do-something where input is new branch name
2. fetch/pull main
3. Create branch and push it to origin
4. user makes text edits as desired
5. when ready, merge request is initiated with -merge option: edit-text -merge im-gonna-do-something
6. push to origin
7. merge request is initiated and merged as long as pipeline succeeds (squash commits, delete branch when successful)
8. if MR fails, then it's handled online

changed milestone to %Backend book support: Phase 1

added Feature IT admin labels

Sounds easy enough, do you mind if the access token is baked on, or would you prefer people make their own?

bake it on. the less work for this user group the better
