Include introductory videos in "Getting Started" landing page

[geriom]

Feature request

Jerop Kipruto has a series of introductory videos that can be very useful for new Tekton Users:

• Tekton for Kubernetes Cloud-Native CI/CD explained
• Tekton CI/CD pipelines and tasks overview
• Tekton Chains: Extensibility, automation, and security

Use case

Some people prefer multimedia content instead of a wall of text to learn new stuff. We already have these good videos covering the basics, giving them more visibility might help many users.

Great idea, this is something we discussed long ago for the now-defunct 'Try' page. I wasn't aware of these videos, checking them out now 👀

fyi @jerop
