Description:

Running SWAG for the first time I got errors while setting it up to work with Dynu DNS challenge. The code for DNSPLUGIN flag was wrongly named and the .ini config file had the wrong name.

Benefits of this PR and context:

If it's not fixed, every single Dynu DNS user will have to make the same adjustments.

How Has This Been Tested?

I kept making adjustments to docker-compose.yml and the filesystem until there were no errors shown.

dynu is a different plugin and it's abandoned

According to docker logs DNSPLUGIN=dynudns is not a recognized value and dynu is suggested. Could it be a validation issue?

I'm also using dynudns and can confirm these changes have to be made to be able to use the dynu plugin.
I have renamed the ./config/dns-conf/dynu-credentials.ini file to dynu.ini and changed the DNSPLUGIN variable in my dockerfile from dynudns to dynu. After these changes, certbot is successfully generating certs for my domain.
