Competency level not displayed (except within a learning path)

[PhilReedData]

Describe the bug

While developing a learning path, we build the topics first. We can set a competency level (eg beginner) for each topic, and for each material. When viewing the topic on its own page, there is no UI to display the level. When viewing the topic within a learning path, there is a badge to show its level. When viewing the material on its own, there is no UI to display the level.

To Reproduce

Learning path with topics with levels (levels shown): https://tess.elixir-europe.org/learning_paths/data-management-for-researchers

Learning path topics with levels (levels not shown): https://tess.elixir-europe.org/learning_path_topics

Learning path topic with level (level not shown): https://tess.elixir-europe.org/learning_path_topics/44

Material within LP with level (level not shown): https://tess.elixir-europe.org/materials/elixir-converge-the-why-of-research-data-management?lp=43%3A140

Expected behavior

• Display the competency level for topics on the /learning_path_topics index page (inside the boxes)
• Display the competency level for topic on the /learning_path_topics/id individual pages (on the left)
• Display the competency level for material on the /materials/id individual page (on the left)

Additional context

Raised at Taxila LP training session, taken to TeSS Dev meeting.
