Many elements in the Tekton UI plugin are missing testIds, roles, names etc., making them difficult to locate and test using automation.

Example:

In this screenshot:

• there aren't any testIds used for any of the elements
• graphical symbols are missing both roles and names
• roles for multiple elements such as pipelinerun's name, vulnerabilities, status are `generic`
• vulnerabilities counts are floating `spans` with no identificators
• status checkmark is missing any form of identification
• role used for the inner part of status cell is `paragraph`

Proposed solution:
Adjust roles and names of the components and assign an unique testId to each element.
