Link search does not prioritise Posts

[getdave]

For general Link searches which haven't been preconfigured to respect a particular type then Posts should always be favoured in the results above other types such as Taxonomy or Media...etc

Since @getdave mentioned "We could look into this more if there is sufficient interest on this Issue." I wanted to note that gizmo2501 is experiencing issues with linking that could be resolved by the ability to customize results: Linking is prioritising attachments instead of posts

#67563 is experimenting with weighting slightly towards Posts in the results.

The Playground link should appear here soon which will allow anyone to test this PR.

Is this why, from 6.7.1 onwards, my link searches now show attachments before posts? There was a marked and annoying change going from 6.7 to 6.7.1 that I can't see overtly mentioned in the changelog.

When I first noticed it, I rolled back to 6.7 to check, and the issue disappeared. Then I moved to 6.7.1, and it came back.

Search results used to prioritize posts, which was ideal for internal linking. Now, I get attachments at the top, and in 20 years of blogging, I have never needed to link text to an attachment.

Closing in favour of #63683
