[NEW CHECK] jsonConfig: new options

[mcm1957]

I'm sure that

• This issue does not report a false-positive detection (use dedicated template for this)
• This issue does not request a change or removal of existing check (use dedicated template for this)
• There is no other (open) issue with the same topic (use the search!)

Description of check to be added

• (@GermanBluefox) Added horizontal option for select component with format: "radio" to display radio buttons in a row
• (@GermanBluefox) Added icon option for select component options to display icons next to labels

--> admin >= 7.8.21
