Wrap the title in the Link Control edit screen

[TimBroddin]

What?

This PR makes long titles in the Link Control edit screen wrap to multiple lines.

When a title can't be retrieved through the API, the link's text is shown as the title instead. This causes a very long line that overflows, making the edit & unlink icons inaccessible.

Why?

It partially fixes this issue.

How?

Added word-break: break-word; to .block-editor-link-control__search-item-title

Testing Instructions

1. Checkout this branch
2. Type a long text without spaces
3. Select the link control and link it to a non-existing domain such as http://thisdomainwillnotgiveyouanyinfo.com
4. Verify that the title is split on multiple lines

Hi @TimBroddin,

I came across this PR when I was checking PRs that had not been active for a while. This issue appears to have been resolved in #53356, although with a slightly different approach.

I would like to close this PR, but I appreciate all of your work.
