Description
From https://github.com/twbs/bootstrap/pull/37780, when our docs website is loaded, the theme switch gets automatically the focus which causes an issue of a11y since we can't go directly on the skip links.
I suppose that this modification was rather made to only give back the focus to the dropdown when a change is made and not during the init phase.
In order to understand what I'm saying, simply load https://twbs-bootstrap.netlify.app/. The focus (blue outline difficult to see) is automatically on the dropdown, then press Tab; "New in v5.3" will be focused instead of the skip links.
I tried to isolate the init phase in the script to force the focus only after. Please double-check that the a11y modifications made in the previous PR are still OK but it seems so.
