[BUG] Erlang package versions specified in the requirements are missing from the external repository (RedHat/CentOS).

[przemyslavic]

Describe the bug
Erlang packages in the version specified in the requirements.txt file are missing from the RabbitMQ Erlang repository.
It looks like new patches have been uploaded and old packages have been removed.
The script download-requirements.sh fails with error ERROR: repoquery failed: package erlang-23.1.4 not found.
Older epicli versions are also affected: ERROR: repoquery failed: package erlang-21.3.8.7 not found.

How to reproduce
Steps to reproduce the behavior:

1. Deploy any RHEL/CentOS cluster (repository vm is enough to reproduce)

Expected behavior
The cluster has been deployed successfully (epirepo has been set up with no issues)

Environment

• Cloud provider: [all]
• OS: [RHEL]

Packages changed to version 23.1.5, repository changed to bintray.
Tested epicli apply and epicli upgrade. After the fix it works fine.

It requires backporting to all previous epicli versions.
