FIX: Do not log client site setting deprecations (#24237)

For deprecated site settings, we log out a warning when
the old setting is used. However when we convert all the client
settings to JSON, we are creating a lot of log noise like this:

> Deprecation notice: `SiteSetting.anonymous_posting_min_trust_level` has been deprecated.

We don't need to do this because we are just dumping the JSON.
