Consider adding a TOC at the top for the configuration page

Description

cmd + F on that page and the user can immediately see e.g. S3 in the TOC - see https://capture.dropbox.com/CnTmk1eYveBsAYIk

Still, some find that right side TOC hard to navigate, so it could be a good idea to add a TOC at the top of that page (not only on the right)

• https://kestra.io/docs/configuration#internal-storage-configuration user expected to have a link to s3, gcs, etc configurations and a list of storage backends available

@elevatebart do you have an idea of how we could automatically create an inline TOC in the same way we show it in the right sidebar?

for docs writers, maybe this could be exposed using sth like this?

::toc
::
