Table of contents: add button to close outline from itself

[mejo-]

Describe the bug
The table of contents can only be opened and closed by navigating to the headings submenu in the menubar. While this is fine for opening the outline, it feels quite cumbersome for closing it. We should add a button to the outline view to close it from itself.

Sorry, I only tested the outline on Collectives and there the heading and close button were hidden by the menubar. I fixed this now by adding the following in Collectives:

[data-text-el='editor-container'] .editor--outline {
	z-index: 10021;
}

Well, the better solution would be to remove top: 104px from

text/src/components/Editor/EditorOutline.vue

Line 66 in 9a45c93

top: 104px;

. What was the reason that you added it @vinicius73?

I'm working in this approach.
