Description

Fixed the item-edit.cy.ts regularly failing because sometimes the <div role="row"> in the <ds-dso-edit-metadata-value> doesn't contain children with role="cell" when the accessibility checks are run. This PR also contains some other minor UI improvements.

Instructions for Reviewers

List of changes in this PR:

• Fixed the item-edit.cy.ts test, to prove this I ran the test with the fix 50 times in the CICD and it doesn't fail anymore.
• Fixed UI issue where the tooltip was sometimes rendered behind the header based on it's z-index and when there is a lot of text. To fix this I added the container="body" to the HTML tag with the tooltip.
• Fixed COAR link on /info/coar-notify-support not working and replaced the logo with an SVG to save a few kb 😅
• On screens smaller than 768px the ds-community-search-result-list-element is not aligning like collections and communities
  
• Fixed <ds-my-dspace-qa-events-notifications>'s logo sometimes overflowing out of the notification
  
• Accessibility: Added missing roles to comcol tabs & added alt attribute to the DSpace logo on the logout page
• Replaced the PNG logos of the login & logout pages with the SVG version in order to retrieve one less asset

👍 Thanks @alexandrevryghem ! This all looks great. I've tested all the various changes mentioned in the description and they all appear to be working as described. Also verified linked issue is fixed.

@alexandrevryghem : I'm just now realizing that this probably should be partially ported to 7.x. The same item-edit.cy.ts issues exist there, along with some of these minor UI issues.

I'm going to flag this as port to dspace-7_x until one of us gets to it. There's no rush (the next 7.x release won't go out until after 8.0 is released), but I don't want to forget this. If you don't find time, I might be able to eventually help port this one.
