[ES|QL] Clicking the editor closes the documentation popover

[stratoula]

Summary

Part of #166907

Fixes the problem with the eui popovers and the monaco editor. I am not sure why it is happening. I think it is due to the third party library that eui uses to detects the outside clicks.

What I did to fix it:

• Wrap the documentation popover in an EuiOutsideClickDetector
• I force monaco editor to focus onMoyseDown

This solves the problem on the documentation popover but not on the SuperDatePicker because I don't have a way to force it to close. I will ping the EUI team

Tested and now the popover closes when clicking outside. 👍
The only annoying thing I found is that, in Safari and only sometimes, when clicking on the ES|QL editor the query gets all selected rather than just set the cursor at the end/in the clicked position. But not a blocker 🚀
