Redirection to newer getting started tutorial

[peterblazejewicz]

As you are probably aware, the docs/tutorials/build-your-first-blazor-app.md should redirect to https://docs.microsoft.com/aspnet/core/tutorials/build-your-first-razor-components-app, but it seems that resulting documentation page is not rendered correctly: https://blazor.net/docs/tutorials/build-your-first-blazor-app.html

Let's figure out redirection in DocFX

Just realized current docs are now using standard documentation pages, so there is simply cached content. Still better should be just a markdown link on that page

We're going to be dumping this repo entirely soon. At that time, we'll be redirecting at the domain-level.

This one was missing a quote. Thanks for letting me know. I'll patch that now.
