EPEL-ANNOUNCE Re: Upcoming removal of rust2rpm + major Rust packaging toolchain update for EPEL 9

[Maxwell G]

We have submitted the new Rust packaging toolchain to EPEL 9:
https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2023-fecd6bbae1
Please help test and provide karma.
This update has been in epel9-next for a couple months now,
but we can push it to epel9 now that RHEL 9.2 that contains python3.11
is GA.

See below for the original announcement.
