7386: Remove reference to Fedora in the readme

[aptmac]

This PR addresses JMC-7386 [0], in which the README should be updated to remove the reference to Red Hat packaging JMC for Fedora (as we don't do that anymore).

I've also added a bit of context for how JMC is available in RHEL 7 and RHEL 8.
