Follow-up from "Add reusable TokenValidityBadge component"

The following discussion from !190538 (merged) should be addressed:

• @dpisek started a discussion:

  suggestion (non-blocking/follow-up): I think we should remove this expectation.

  Testing for the existence of CSS and therefore the visual representation of the component should not be done within a unit test.

  There are a few reasons:

  • Unit tests should focus on component behaviour and functionality rather than styling
  • CSS class names may change during refactoring without affecting functionality
  • Testing styling can make tests brittle and lead to unnecessary maintenance

  It is a small change and since we want to get this out for %18.0 I'll open a follow-up issue where it can be handled. Feel free to assign the resulting MR directly to me 🙂
