Only put major Postgres version in CI task name (#7289)

Making tasks in CI required before merging to master is important and
useful. The way this works is by saving the exact names of the required
tasks in the admin interface of the repo. It has a search box to add
them so it's not completely horrible, but doing so is quite a hassle
since we have so many jobs. So limiting the amount of churn in this list
of required jobs is quite useful.

This changes the names of tasks to only include the major versions of
Postgres, not the minor ones. Otherwise the next time we bump the minor
versions we would have to remove and re-add each of the jobs.
