[fentix]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Installed a new SWAG Container and got a warning because cloudflare will retire the current API
The Linuxserver-CI Bot updated the cloudflare 2.20.0 python package with the commit 95c13d0 which causes a warning.

Expected Behavior

No Warning Message.
(Updating the API to 3.0 or Downgrading the API to 2.19 for now.)

Steps To Reproduce

1. Create a SWAG container with the current lscr.io/linuxserver/swag:latest
2. Use The cloudflare DNS Validation for SSL-Cert generation
3. Look at the output Logs after starting the container.
