Presentation of comma separated values

### Description

When you store a value from a checkbox you get values that are separated with commas.
When you present those values to the end user it doesn't look so good. e.g. `value1,value2,value3,value4`.

I would like to have language support for this presentation that would look like this. `value1, value2, value3 and value4`
Where **and** is changed based on the language selected.

- #1179

Start by locating the frontend component that presents checkbox values and review the existing language or localization setup, including related issue #1179. Done means comma-separated values are rendered with readable spacing and a language-dependent final conjunction, such as “value1, value2, value3 and value4.”
