[community-group] Allow `em` for dimension token (#390)

lukasoppermann has just created a new issue for https://github.com/design-tokens/community-group:

== Allow `em` for dimension token ==
### Before starting

- [x] I have searched [existing issues](https://github.com/design-tokens/community-group/issues) and there is not already an open issue on the subject.

### Summary

Add `em` to the supported values for dimension tokens.

In contrast to `px` and `rem`, `em` are related to the current text size. This behavior can not be easily replicated with `rem` or `px`. 

However in some cases, like inline code in text blocks of different sizes, icons that are placed inside of text, etc. it is important to use `em` as you would otherwise need to define additional tokens for each situation.
