Zoom out: E2E tests

[talldan]

Summary

With the zoom out mode feature landing in 6.7, it'd be great to increase test coverage, especially as bugs are fixed during the RC/Beta phases.

Currently there is an e2e test file, but it's skipped and probably quite outdated:
https://github.com/WordPress/gutenberg/blob/trunk/test/e2e/specs/site-editor/zoom-out.spec.js

It'd be great to add some basic tests, then build up the coverage over time. During the RC/beta, more e2e tests can be added for any bugs that are fixed.

These tests will probably also end up covering Edit/Write mode with the proposal in #65736.

Things to test (please feel free to edit this list):

• Entering zoomed out mode zooms the canvas
• Sections are correctly defined when editing different types of content
• Vertical toolbar is shown for sections
• Reordering sections works correctly
• Inserting new patterns
• Content is editable
• Horizontal toolbar is shown for content
• Double click to exit (see Only exit zoom out on double clicking the section itself #65782)
• Check that the content scales correctly Scaling not one to one when zooming out #65757 Zoom out: wide blocks are shrunken #63519

We need to think about which tests we want to make on the post editor

Can this be removed from the 6.7 project board? I assume this doesn't impact the release directly, right?

I would like to see the Zoom Out feature succeed upon its introduction in 6.7. Test coverage for the available launch seems to be a baseline standard for allowing contributors to test, verify, and assert whether the intended features for 6.7 are doing what they should be doing. Under these guiding principles, I would establish that these end-to-end tests are crucial for 6.7.
