workshop page: materials + lessons section

[JayJ104]

For the lessons section, only create a template collapsible component as in the design. the content of the component will be decided by the leads for each workshop. The workshop page for each week will typically have 0-5 "lessons" examples.

The workshop recording will probably be a Zoom/GMeet recording and the workshop slides will be on Google slides. Use appropriate samples to check the embedding.
