fix(deps): pin development version of MSSDK to avoid stale dependencies

Simply specifying the `develop` branch is cause for problems. Pip will
not reinstall the dependency as it would interpret no change to the
version of the package installed. In turn, the Docker cache layer for
the file would remain unchanged and the dependency resolution would not
be rerun. This would lead to a stale dependency situation in the images.
