Remove YouTube link to obsolete todomvc video

[MikeMcC399]

• closes Outdated todomvc example used in github-actions (Rev2) #5126

Situation

Regarding YouTube video https://youtu.be/zGrAhZkCoUE

• Continuous Integration > GitHub Actions links to Example App Overview which is a YouTube Video from June 2021 with the title "GitHub Actions + Cypress: Example App Overview" that describes using the repo https://github.com/cypress-io/todomvc
• The repo https://github.com/cypress-io/todomvc is based on the legacy Cypress 7.0.0 version and was archived on May 16, 2024.
• There is no other reference to the todomvc app on the above documentation page
• Although there is an active replacement repo https://github.com/cypress-io/cypress-example-todomvc the differences between this newer repo and the archived https://github.com/cypress-io/todomvc are so many that the YouTube video does not fit anymore

Change

Remove the Example App Overview obsolete YouTube video link from the page Continuous Integration > GitHub Actions
