SFD-107 Jira ticket

Removes the merge trigger for the pages deployment workflow leaving only the manual trigger.

Approved, I think this can be merged in now?

I was going to suggest that workflow_dispatch should also be restricted to the main branch but apparently that's not a thing: https://stackoverflow.com/questions/72398993/github-action-workflow-dispatch-how-to-always-use-the-master-branch-remove-o

We could add a step at the start to check if the branch is main and exit if not.

As discussed, we'll leave it as it is for now so people can publish from other branches if desired and revisit if needed.
