In commit 7c8b9f4da8 I intended to make a
copy of the RHEL 9.1 repos under the key "rhel-9" so that the
RHEL 9 distribution, which is currently an alias to RHEL 9.1 (the
current GA) would have valid test repositories available for the test
case generator. Instead, I accidentally replaced the "rhel-91"
repositories with the ones for "rhel-9".
This commit fixes that mistake.
