Block fixtures: Change port to 8889 to placate KSES (#37100)

Unit tests are currently failing on `trunk` (when used with a current snapshot of the WordPress svn or git repo).

Specifically: `Block_Fixture_Test::test_kses_doesnt_change_fixtures` fails for datasets #54 and #55.

Reading WordPress/wordpress-develop#1998, I believe that the reason might be that our KSES routines are verifying that the specified port matches the one of the local install. And since our tests normally run `localhost:8889`, I'm updating the relevant test fixtures (from previously `8888`) to reflect that.
