Bitwarden issue when setting bitwarden_allow_signups to true

[HitLuca]

looks like bitwarden errors out when bitwarden_allow_signups is set to true in the inventory file. The value should be casted as string as such

    - name: Bitwarden Docker Container
      ...
        env:
          SIGNUPS_ALLOWED: "{{ bitwarden_allow_signups | string }}"
