Problem

All CI builds are currently failing due to updates to vendored dependencies being required. Specifically, we run git diff as part of our tests (https://github.com/buzzfeed/sso/blob/master/scripts/test) which fails after the CI process itself tries to update these dependencies.

Solution

Update the required dependencies - changes within individual commits outlined below:

• Commit f243b66 includes changes to go.mod and go.sum from running https://github.com/buzzfeed/sso/blob/master/Makefile#L18-L20. This is ran during the CI process, which then causes errors in our git diff invocations in https://github.com/buzzfeed/sso/blob/master/scripts/test

• Commit f58f94f includes changes to local copies of dependencies, from running go mod vendor (which is ran in https://github.com/buzzfeed/sso/blob/master/scripts/test#L20)

I think larger changes are required to this process to keep the CI/test/builds running cleanly, though that can be addressed separately - this PR aims to unblock the CI/build process.
