Cap Sphinx to avoid docs build failure (#188)

The recent sphinx 3.3.0 release today has started causing doc build failures in CI. This is being caused by an issue with the m2r2 extension used to render the README in the docs builds (see CrossNox/m2r2#13). This commit caps the sphinx version until there is a new m2r2 release fixing compatibility with sphinx >=3.3.0.
