Update DNSDB to v2 and add offset use

[kelvinatorr]

I updated it to use our newer v2 api and added ?offset use so that a user can get all the results allowed for their api key.

$make build && ./subfinder -s dnsdb -timeout 500 -pc ../provider-config.yaml -v -d projectdiscovery.io
go1.20.8 build -v  -ldflags '-extldflags "-static"' -o "subfinder" cmd/subfinder/main.go

I also added DNSDB to the list of Recursive sources because it does support it

$make build && ./subfinder -s dnsdb -timeout 500 -pc ../provider-config.yaml -v -d auth.projectdiscovery.io
go1.20.8 build -v  -ldflags '-extldflags "-static"' -o "subfinder" cmd/subfinder/main.go
