Disable crash logging in debug builds

Now that the Sentry DSN is committed rather than decrypted, every build
carries the production DSN — including local, contributor, and screenshot
builds, which previously fell back to the dummy DSN in
`gradle.properties-example`.

`analyticsIsEnabled()` defaults to `true` when the preferences bucket is
absent, so nothing else stopped a fresh contributor build from reporting
into the production project.

This matches `WPCrashLoggingDataProvider` and WooCommerce, which both keep
debug builds out of Sentry. Prototype builds are `Debug`, so they stop
reporting too — consistent with wpandroid, whose prototypes are already
silenced the same way.
