[Docs - Quickstart] - Requesting PHP Symfony

[hotwebmatter]

To start a Symfony project, should I modify the PHP Drupal or PHP Laravel quickstart?

[hotwebmatter]

Never mind, I found these:

• Symfony 5 Demo Application
• Symfony 6 Demo Application

Might be nice to add this to the QuickStart templates. Probably the gitpod-io project should be updated to track the latest upstream changes, as there are hundreds of deprecations in the Symfony 5 demo app.
