 layout.html: Revert patch forcing Spinx to >= 6.0

 Unfortunately, updating past Sphinx 5.x results in unordered bullet
 lists not formatting correctly as show in a screen capture attached
 to #4928. Revert this patch until the issue is resolved and output
 is reviewed for other potential issues.

     Subject: [PATCH] eng: Fix builds for newer Sphinx versions (>=7)

     The current Sphinx theme depends on the `style` parameter which got
     deprecated in v5.1 and finally got removed in v7. Now, the `styles`
 key
     should be preferred which is a list of stylesheets. This commit
     implements this change.

 Updates #4915.
 Updates #4928.
