Administration: Remove self-reference ("we") in WordPress Admin.

This changes updates many strings to remove self-references to an undefined "we" collective across the WordPress Administration.

The goal of this change is to better match the guidelines and recommendations set forth in the make/core handbook, specifically:

> the word "we" should be avoided (…) unless its made very clear which group is speaking.
