[DOCS] Out of date reference minion configuration for retry_dns

Description
There is some inconsistency of the retry_dns option for salt minion

https://docs.saltproject.io/en/latest/ref/configuration/minion.html#retry-dns
... Defaults to 30 seconds. Set to zero if the minion should shutdown and not retry.

From a Windows minion with failover master configuration

salt-call state.apply

[CRITICAL] 'master_type' set to 'failover' but 'retry_dns' is not 0. Setting 'retry_dns' to 0 to failover to the next master on DNS errors.`
...

Suggested Fix
What did you expect to see in the documentation that is missing or needs updating?

I'll test with a dummy master DNS entry to see if the failover still happens with retry_dns is 0

Type of documentation
This is from the Saltstack reference configuration for minion

Start with doc/ref/configuration/minion.rst at the retry_dns reference and compare its stated behavior with the failover warning in the issue. Reproduce the Windows failover case using a dummy master DNS entry and retry_dns set to 0. Done means the documentation accurately describes the verified retry and failover behavior.
