Wrong documentation for KNX Secure

[KGuetter]

Feedback

https://deploy-preview-22203--home-assistant-docs.netlify.app/integrations/knx/#knx-secure states that the knykeys file should be exported from the project security details.
For ETS6, this is wrong. The knxkeys file must be created by the "Export Interface Information" command on the IP Tunnel that shall be used for HA.

Hi 👋!
Thanks for pointing this out!
How can one export a keyring for use with Secure Routing and DataSecure in ETS 6? Afair in ETS 5 the backbone key wasn't included in the keyfile when not exporting everything (eg. a single tunnel).
Not sure how this works in ETS 6 as I currently don't have a license for it.

In case of Routing, you need to put an interface (e.g. the Gira Secure IP Dummy) on the backbone and export its Interface Information file.

BTW: all this can be tested with ETS 6 Demo, no license required.
