cloudflare_dns: Fix setting SRV records with a root level entry (#5972)

* cloudflare_dns: Fix setting SRV records with a root level entry

* cloudflare_dns: Remove the part which deletes the zone from the SRV record name

The cloudflare API accepts the record name + zone name to be sent. Removing that, will guarantee the module to be idempotent even though that line was added ~7 years ago for that specific reason: ansible/ansible-modules-extras@7477fe5

It seems the most logical explanition is that Cloudflare changed their API response somewhere over the last 7 years.

* cloudflare_dns: Update the changelog fragment

(cherry picked from commit 094dc6b)
