web: extract `WebHoverOverlay` story into a separate file
Created by: valerybugakov
Description
This PR is a preparation for the Code Intel redesign work.
Changes
- Extracted
WebHoverOverlay
stories into a separate file and moved them into theweb
package. - New story uses the
WebHoverOverlay
component directly instead of usingHoverOverlay
and providing web props. It's handy because now we have one source of truth for web props. - Fixed inconsistent
infoAlertClassName
prop inWebHoverOverlay
story. - Extracted fixtures into separate files.
