Subject: [PATCH] Fix _check_dns_entries for suggested apex domain
 substitutions for --domain-alias

Current checks don't support @.domain.tld or .domain.tld, which are suggested to be used instead of the domain apex with --domain-alias at https://github.com/acmesh-official/acme.sh/wiki/DNS-alias-mode#7-challenge-alias-or-domain-alias
This fix removes "@." or "." at the beginning of the domain, so the correct domain will be checked.
