Fix grammar in the "Server Administrator" section

[adiati98]

Description

We need to fix the grammar in the "Server Administrator" section by addressing the Vale warnings and suggestions. Feel free to update and improve the copy when you see fit.

How to fix

1. Open the file at: docs/contributing/server_administrator.rst
2. Remove the .. vale off and .. vale on lines in the file.
3. In the terminal, assuming you're in the docs directory, run vale contributing/server_administrator.rst command.
4. Address each vale errors, warnings, and suggestions as much as possible. You can check if they're fixed by running the vale contributing/server_administrator.rst command again.

Note

Please read and follow our Style Guide when fixing/updating writing style and grammar in our docs.
