* Increase code coverage in acmedns
* More testing of ReadConfig() and its fallback mechanism
* Found that if someone put a '"' double quote into the filename that we configure zap to log to, it would cause the the JSON created to be invalid. I have replaced the JSON string with proper config
* Better handling of config options for api.TLS - we now error on an invalid value instead of silently failing.
added a basic test for api.setupTLS() (to increase test coverage)
* testing nameserver isOwnChallenge and isAuthoritative methods
* add a unit test for nameserver answerOwnChallenge
* fix linting errors
* bump go and golangci-lint versions in github actions
* Update golangci-lint.yml
Bumping github-actions workflow versions to accommodate some changes in upstream golanci-lint
* Bump Golang version to 1.23 (currently the oldest supported version)
Bump golanglint-ci to 2.0.2 and migrate the config file.
This should resolve the math/rand/v2 issue
* bump golanglint-ci action version
* Fixing up new golanglint-ci warnings and errors
