[24.0] Improve workflow creating/saving UX

The UX is improved with the following changes:
- 🎨 The `+ Create` button on the `WorkflowList` shows the tooltip "Open workflow editor" instead of "Create new workflow"
- 🎨 For a fresh, empty workflow editor, where the user hasn't saved yet, the following text has been added next to the workflow name header: "_(Click Save to create this workflow)_"
- 🐞 We ensure the reload page confirmation is triggered on changing workflow name and annotation as well.
- 🐞 We also ensure that the router reload confirmation flag is reset on route change, since sometimes, the confirmation was not cleared when the route changed and the confirmation alert was shown needlessly.

Fixes galaxyproject#18609
