Remove member names from some charters

Problem/Motivation

The individuals members of a working group change independently of the charter. Therefore, the charter should direct to where the current members are listed.

Steps to reproduce

View the documentation, infrastructure and the licensing charters.

Proposed resolution

Remove the names are add where the names should be listed.

Only the Documentation Working Groups, Drupal Licensing Working Group and Drupal.org Infrastructure Working Group are changed here because the memberships is listed elsewhere.
