Add contextMenu prop to Actions and ListTasks

[jescalada]

Hey, I just made a Pull Request!

Related: #27448

Changelog

• Added contextMenu prop to scaffolder plugin's ActionsPage and ListTasksPage
  • Fixes issue when passing { editor: false } as the contextMenu prop, where the /create/* routes don't remove the editor link

Please let me know if adding/modifying tests is required for this PR!

Note: I edited a line in ScaffolderPageContextMenu which used to check that either the editor OR the actions callbacks were present. If not, the context menu would not render. I'm not sure about the purpose of this line, but adding additional checks for the other callbacks is required to render the context menu on /create/actions/ when { editor: false } is set.

Screenshots

When { editor: false } is passed to the ScaffolderPage contextMenu prop:

/create

/create/actions

/create/tasks
