Unable to disable hostname lookups if Settings.php is read only

[jdarwood007]

Description

" Disable hostname lookups" is greyed out if you have Settings.php read only. This is a database based option and shouldn't be tied to the restrictions of the readonly Settings.php

Steps to reproduce

1. Make Settings.php read only
2. Visit ACP > Maintenance > Server Settings > General

Environment (complete as necessary)

• Version/Git revision: de9946f
• Database Type: N/A
• Database Version: N/A
• PHP Version: 8.2

I swear there was another issue/PR related to this that fixed this in the past.
