Downloading a wireguard conf on mobile makes the file end with .txt instead of .conf

[Sleuth56]

Describe the bug When you create a new wireguard VPN device on an android device using either Chrome or Firefox and download the wireguard conf file it ends with .txt instead of .conf like it does when downloaded on a desktop operating system. This causes issues with the wireguard android app which wants the file to end with .conf

To Reproduce Steps to reproduce the behavior:

1. Login to your defguard account on an android device
2. Create a new device
3. Select it to be a Wireguard client
4. Get to the page with the QR Code
5. Download the wireguard conf

Expected behavior For the file to end with .conf like it does when downloaded on a desktop PC OS.
