add a "rollback" feature if the docker step fails

[evanugarte]

lets add a new field to the yaml like

enable_rollback: true

when this is enabled, the process of pulling and updating should go like this

• check if enable_rollback is set
• if so, make a new branch like DATE-TIME-main like 20260103-171022-main, this is the copy of main before we pull from github
  • store the name of this branch as a variable, we will use it later
• switch back to main

happy path

• pull from github
• try docker compose up
• if it works, delete the temporary branch we created

sad path

say we are on main and docker is breaking, we need to roll back

• we need to make main match 20260103-171022-main, what github command can do this?
• assuming git command works, delete our temporary branch 20260103-171022-main
• retry docker compose up

if we do a rollback, we should push an embed saying that it failed
