[PATCH 1/1] eng: Fix builds for newer Sphinx versions (>=7)

[Utkarsh Verma]

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.
