We should not need to be explicitly adding transitive dependencies to
requirements_formatting.txt.in to enforce a higher version is used. We
also should always be using == to ensure a strict version match, not
just a compatible version (~=). This patch removes transitive
dependencies introduced in 6fdf93c5d812197dd5dc9362f324b944105b2e8e and
updates the lockfile (although only unnecessary packages are removed).
