Missing /api/server/qrcode.svg after upgrade to v4.50.2
### Describe The Bug

We use the rest api call to /api/server/qrcode.svg to get the QR-Code in SVG format for displaying the pairing qr-code for apple homekit easily in our system where we are using homebridge.
After upgrading homebridge-config-ui-x from version v4.41.2 to v4.50.2 this feature is not available anymore.
Has the link changed or is this feature missing ?
I still can get the pairing code number from /api/server/pairing
But don´t know how to convert that into a qr-code link.

Our system is running on
OS: Linux 4.14.52 arm ( Ubuntu 16.04.7 LTS 4.14.52 )
Node.js v16.19.0

Thanks for your attention.
