Add possibility to group states in webserver

[spacemanspiff2007]

Describe the problem you have/What new integration you would like

I have multiple states and i would like to group them logically in the webserver. Currently the order is random.

Please describe your use case for this integration and alternatives you've tried:

If states can be grouped logically together then it's easier to keep an overview over the states

Additional context

Maybe an additional property on the item (e.g. group) or an additional field on the webserver groups which is a list which contains lists of ids.

Please check if webserver v2 (default since) satisfies your needs.

I can't find any hint in the docs how grouping of sensors would be possible with v2. Maybe I am missing something but I think it's not implemented.
