Workflow license and creator edit keyboard access

[itisAliRH]

Closes #18915. This PR improves the LicenseSelector and CreatorEditor ui and makes them keyboard accessible. It migrates LicenseSelector to composition API and typescript, uses GalaxyAPI to fetch license options, and uses the MultiSelect component, simplifying the license handling steps.

Can you also remove the save/cancel buttons ? We don't do that anywhere else in the editor

@mvdbeek The creator form is using it:

Should I remove buttons in both components or not? If yes, does replacing them with only small icons work?

[hexylena]

oh those buttons are much nicer click targets than the absolutely miniscule 'save' icon that's currently used. Would be very happy to have those larger targets for my poor mouse aim (the reason I use the keyboard to start with)

[mvdbeek]

Yeah, I think removing those save button would be great.

+1 to removing them and saving consistent with other workflow changes.

Thank you all for the comments. So I will remove the buttons and show only the licence selector on the editor.
