python3-ldap (Renamed to ldap3)

The `python3-ldap` project has been renamed to `ldap3`. This entry documents `python3-ldap` as a deprecated library and strongly advises users to migrate to `ldap3`, which is the actively maintained and current library for interacting with LDAP servers in Python. `ldap3` provides a comprehensive, modern, and high-performance feature set for LDAP client operations, including secure connections (LDAPS/StartTLS), asynchronous operations, and various authentication methods. The current version of `ldap3` is 2.9.1, and it maintains a steady release cadence.
