Libssh2 RPM is available in the Appstream8.latest RHN channel.  The current version is libssh2-1.8.0-8.module+el8.0.0+5339+ebcc8ca7.1.x86_64.rpm.  (I just checked).

Packages in the RHN are never removed.. but you may not be able to
install/rebuild etc those packages without a lot of work. The package
libssh2 is available in the modules with metadata of
virt-devel:rhel:8000020190828150510:f8e95b4e and
/virt-devel:rhel:820190226174025:9edba152 however the newer modules of
do not have it anymore.

So the modules you are looking at are from 8.0 and not 8.1 or 8.2 ..
so while it shows up in the latest.. it is actually not the latest and
is a 'dead' package. People doing newer installs or using CentOS will
not have access to it.

However, if there's a later version available in Appstream8.latest, it'll pick that up (during the "upgrade to latest & greatest").  I believe we've grabbed that libssh2-1.8.0-8.module+el8.0.0+5339+ebcc8ca7.1.x86_64.rpm from AppStream8.latest and we've staged it.
