The PR is likely ready to be merged. No tests are needed as no important environment files, nor python files were modified by it. However, committers might decide that full test matrix is needed and add the 'full tests needed' label. Then you should rebase it to the latest main or amend the last commit of the PR, and push it with --force-with-lease.

There are some spelling errors in the docs build:

Incorrect Spelling: 'Honours'
Incorrect Spelling: 'honour'

You could add this spelling to https://github.com/apache/airflow/blob/main/docs/spelling_wordlist.txt too if you think no spelling/word change is needed :)
