Allow pressing e to edit inside the yaml view

[DerRockWolf]

Would be very handy when one first opens the yaml view and then noticed that something should be edited.
Currently you would have to go back and then press e, which can be confusing when there are still objects from the watch filling the table view.

Makes sense, lets do it! Tracking it in #765.

Good point about the watch too - backing out while rows are still loading can move the cursor, so you could end up editing a different object than the one you were reading.

Scope:

• e works in the YAML and describe views and edits the resource shown in the document, not whatever row is selected in the table.
• Read-only mode and the Flux-managed warning behave the same as in the table.
• The document reloads after the editor closes, so you see your change right away.
• Not in the decoded Secret, diff or events views. kubectl edit shows encoded data, which would be confusing next to the decoded view.

PR coming soon :)

Nice that you've also added it to the describe view 👍
