Add workflow email action (#7279)

- Add the SAVE_EMAIL action. This action requires more setting
parameters than the Serverless Function action.
- Changed the way we computed the workflow diagram. It now preserves
some properties, like the `selected` property. That's necessary to not
close the right drawer when the workflow back-end data change.
- Added the possibility to set a label to a TextArea. This uses a
`<label>` HTML element and the `useId()` hook to create an id linking
the label with the input.
