Revert "chore(.requirements) bump OpenSSL version to 1.1.1e (#5698)" (#5727)

This reverts commit 7d18f807f94a711c15e73141ad89cb4ce4289ffa.

Reverting the bump for the time being due to a change in behavior from
OpenSSL. This avoids unexpected "crit" error messages from NGINX, and
should be acceptable given the security issues fixed by OpenSSL 1.1.1e is
considered "very difficult to perform and are not believed likely"
(https://www.openssl.org/news/vulnerabilities.html#2019-1551).
