source-zendesk-support: update capture snapshot

Over the weekend, it looks like Zendesk Support added a
`configuration.explore_reports` field to all custom roles returned via
their API. This is causing our `source-zendesk-support` capture snapshot
test to fail, so updating the snapshot will let our tests pass.

Since `configuration.explore_reports` isn't included in the official
Zendesk Support docs yet, I'm holding off on adding that field to the
stream's schema in case Zendesk removes it.
