Custom provider with vhost address style does not work

[sa7mon]

Steps to reproduce

1. Spin up the dev mitm docker compose profile
2. Edit config.yml to be:

providers:
  custom:
    insecure: true
    endpoint_format: "https://$REGION.linodeobjects.com"
    regions:
      - "fr-par-1"
    address_style: "vhost"

3. Scan any single bucket: go run main.go -provider custom -bucket google.com
4. Observe the requests listed in mitmproxy are being sent to https://fr-par-1.linodeobjects.com instead of https://google.com.fr-par-1.linodeobjects.com
