Use Let’s Encrypt dns-01 challenge during self-hosted installation

I may have missed it. But I can’t see in the code where one can specify dns-01 with a wait time for a Let’s Encrypt challenge on ./bitwarden install.

Self-hosters running in VMs behind proxies will have real issues using other, non pause-able LE challenges.

Without this capability one has to run certbot on the VM and arrange to have certs renewed, copied to ./bwdata/ssl and restart the nginx container on a cron schedule.

Not hard but not convenient.
