Missing documentation in the wiki for the DNS rewrites enabled flag

### Prerequisites

- [x] I have checked the [Wiki](https://github.com/AdguardTeam/AdGuardHome/wiki) and [Discussions](https://github.com/AdguardTeam/AdGuardHome/discussions) and found no answer

- [x] I have searched other issues and found no duplicates

- [x] I want to request a feature or enhancement and not ask a question

### The problem

The [wiki page](https://github.com/AdguardTeam/AdGuardHome/wiki/Configuration#configuration-file) for the configuration does not mention the `enabled` flag for legacy DNS rewrites.

### Proposed solution

> rewrites: List of legacy DNS rewrites, where domain is the domain or wildcard you want to be rewritten and answer is IP address, CNAME record, A or AAAA special values. Special value A keeps A records from the upstream and AAAA keeps AAAA values from the upstream. The enable property is the status of the rewrite (enabled/disabled).

> 'enabled': true
