web fix(test-runner): unify visual-written representation of skipped tests

What I did

Unifying Visual and Written Representation of 'Skipped' Information for better comprehension - cognitive accessibility.

Presently, when a test is skipped, the visual representation uses a red "X" symbol, while the written summary denotes the skip with a gray label.

To enhance understanding and cognitive accessibility, I suggest introducing a new visual symbol, “-,” rendered in a subdued color, to complement the existing skipped label. This alignment of visual and written representations aims to improve clarity and consistency.
