Only show "Edit sketch" button when code pane is focused with sketch selected (#5691)

* Only show "Edit sketch" button when code pane is focused with sketch selected

Closes #4273. WIP until tests are updated, since this will impact many
that look for the "Edit sketch" button.

* Start removing "edit sketch" point-and-click from E2E

* Update more E2E tests

* Update more tests that assumed Edit Sketch button

* A snapshot a day keeps the bugs away! 📷🐛
