a11y: Add "title" to <a> tags of PHUIObjectItemView images
Summary:
Links should have a discernible name per https://dequeuniversity.com/rules/axe/4.10/link-name
`PhabricatorRepositorySearchEngine::renderResultList()` renders `PHUIObjectItemView` objects, thus add `title` parameters to <a> links.
Ref T16072
Test Plan:
Go to http://phorge.localhost/diffusion/ and inspect the `<a>` element surrounding the folder icon link for each listed repository.
Go to http://phorge.localhost/people/ and inspect the `<a>` element surrounding the folder icon link for each listed repository.
