Links to Glitch starter project should open in new window

[beaucarnes]

Some challenges link to a Glitch starter project. The link opens in the same window. It would be more user-freindly if the link opened in a new window/tab. Most people clicking on that link will want the fCC page to still be open so they can submit their project. This also applies to GitHub link.

Example url: https://deploy-preview-45--freecodecamp-learn.netlify.com/information-security-and-quality-assurance/advanced-node-and-express/use-a-template-engines-powers

@Bouncey can this be closed? This really belongs on the curriculum repo and the PR was already closed.
