[horde] Horde 5.2.23 ActiveSync autodiscover JSON support

it's my Android-Mail (version 2022.08.07.469547715.Release) App that  
requests the JSON endpoint. 

I tried to set up ActiveSync on the phone by using its settings.

I see the app version is relatively recent, so maybe it's a new thing?  
Not sure.

Ok, yes, changing the protocol value to lower case makes it return the  
right content.

Thank you very much for adapting the code. 

I have to wait though, until Debian packages your changes, since I'm  
using the Debian packages.

Best regards,
