Upgrade Gitaly client to v1.74.0
Closes #231 (closed)
There was a mistake in an earlier update to the Gitaly client (see gitaly!1637 (merged)). This bump integrates the corrected version of the Gitaly client.
This bump was done by running go get gitlab.com/gitlab-org/gitaly@v1.74.0
in the folder containing the module file.
