Add navigation by contexts in the content bank

As a course creator/editor/teacher/admin
I want to be able to navigate between contexts that I have access to in the Content bank
so I can manage it in a better way.

In order to improve the user experience of the Content bank, we would like to add navigation by contexts from the Content bank without having to navigate through the different Moodle pages. This way, from the Content bank we could access the system, course category and course contexts in one click.

Acceptance criteria

• We could change the context that I have access to from the Content bank.
• We couldn't change to the context that we don't have access.
