fix: [Obs Applications > Services][KEYBOARD]: "What are these metrics?" tooltip icon must receive keyboard focus

[alexwizp]

Closes: https://github.com/elastic/observability-dev/issues/3402

Description

The Obs Applications > Services view has a "What are these metrics?" icon that exposes a tooltip when hovered, but that tooltip cannot take keyboard focus, making it unavailable to keyboard users. Screenshot attached below.

Steps to recreate

1. Open the Obs Services view
2. Tab through the table, until focus is on an element after the "What are these metrics" question mark icon
3. Verify the icons in the table row(s) never receive focus and the tooltips never become visible

What was changed?:

1. EuiToolTip -> EuiIconTip
