set MinLinuxServerVersion for RHEL 9 to 6.0.0 (#783)

6.0.0 is the earliest supported version for RHEL 9, so we should not
push new mongo-tools releases to the repos for earlier server versions.

RHEL 93 was previously succeeding, but the 5.0.0 repo for RHEL 93 exists
by mistake and will be removed soon, so I'm adding the minimum version
to that too
