deploy: Fix deploy defaults for non-zero flag values (e.g. maxDeletes, invalidateCDN)

This was broken in the config rewrite in Hugo 0.112.0.

The workaround is to be explicit about setting these flag values (even if just using the defaults), e.g.:

```
hugo deploy --invalidateCDN --maxDeletes 256
```

Fixes #11127
