update sphinx dependencies to fix jinja2 doc build error

[imatiach-msft]

Description

The website build (GitHub Pages / website-build-and-deploy) seems to be failing with jinja2 error. This PR updates sphinx package, which should work with the newer version of jinja2, in order to fix the workflow error.
