* Provider Porkbun: Delete Default Parked DNS Entry for *.domain.tld
Description:
By default, Porkbun creates default ALIAS and CNAME domain records pointing to `pixie.porkbun.com` (Porkbun's parked domain website)
The current logic flow prior to this PR would look for an A or AAAA domain record, and if none exists, attempt to delete the ALIAS record for any subdomain.
This updates the logic flow to only look for a conflicting ALIAS record for the top level `domain.tld`, and a conflicting CNAME record for the `*.domain.tld`. Additionally, we verify that the content of this record matches `pixie.porkbun.com` and we only delete for the expected default values.
If the value does not match the expected `pixie.porkbun.com` we produce more helpful error messages.
Test-Plan:
Created a new domain.tld on Porkbun
Verified the default records were created:
`ALIAS domain.tld -> pixie.porkbun.com`
`CNAME *.domain.tld -> pixie.porkbun.com`
Started DDNS-Updater
Verified that both domain records were successfully deleted and updated
Reset the ALIAS domain record to point to `not-pixie.porkbun.com`
Reset the CNAME domain record to point to `not-pixie.porkbun.com`
Started DDNS-Updater
Verified that both domain records failed with the expected conflicting record error message.
- add `deleteDefaultConflictingRecordsIfNeeded` method
- handle non conflicting errors from `deleteSingleMatchingRecord`
- simplify comments by linking to documentation
- improve error wrappings

- retro-compatible change: keep using host/owner if set
- otherwise extract owner and eTLD+1 from domain field
- documentation updated to only use the `domain` field
- Remove `IPV6_PREFIX` environment variable (unneeded) and remove associated code
- Update all documentation for each provider supporting IPv6
- Build IPv6 as prefix:suffix when getting it from a public IP source for each record IPv6 suffix parameter
- Automatically disable provider_ip if public ip is IPv6 and IPv6 suffix is set (they are not compatible with each other)
