[ES|QL] Editor commands using stale dependencies

[davismcphee]

In #244453 a fix was added to the ES|QL editor to prevent re-registering Monaco commands on every React render. However, now those command callbacks are using stale dependencies (whichever ones exist when editorDidMount is called).

This causes issues in Discover such as ES|QL controls not being created as expected, and command + return not triggering searches. It likely also affects other places where the editor is used.

This video demonstrates the controls and search issues along with the console errors logged:

This PoC fixes the controls problem to demonstrate the issue, but the real fix for all stale dependencies would be more involved: #245454.
