Implement adding component to empty layout without dnd

This brings back every skip added in 🐛 Temporarily skip intermittently failing e2e tests Active , and I've rerun the Cypress tests many times and they pass every time.

• components-operations, empty-canvas and publish-button now add a component to the empty layout by clicking the component instead of dragging it. (turns out the UI already does this! Just no affordance to make it evident)
• global-regions was unskipped but no changes as the drag and drop operation is never in the canvas area. Seems to be passing
• The skip added in components-slots earlier today was removed, but only because a skip is already present on the higher level describe() that was added last month. The scope of this issue is only to remove skips added in #3500549

🥳 for more reliable tests! (And running the entire test suite again.)

This restored all tests that 🐛 Temporarily skip intermittently failing e2e tests Active temporarily skipped.

FYI: when this was merged, component-operations.cy.js failed during the 0.x test run 🙈 But it failed ~20 LoC earlier than the change here.

Failure:

                    Expected: 	"findByText(`The Entire Node 1`)"

Relevant test code:

    cy.openLibraryPanel();
    cy.get('.primaryPanelContent').within(() => {
      cy.findByText('Sections').click(clickDefault);
      cy.findByText('The Entire Node 1').should('exist');
    });
    cy.get('.primaryPanelContent')
      .as('panel')
      .should('contain.text', 'The Entire Node 1');

Automatically closed - issue fixed for 2 weeks with no activity.
