Migrated HelloWorld tutorial to F' community

[hAkselS]

This PR removes the hello world tutorial from NASA/fprime repo and references the hello world on fprime-community in all NASA/fprime READMEs

Something I realize just now is that by doing this (removing the entire folder), the https://nasa.github.io/fprime/Tutorials/HelloWorld/Tutorial.html link will die, however that's the link that's in master's README and there's not much we can do about this until next release.

Hmm yeah I see the problem there, but won' the old tutorial live there until the next release too?

The docs are built out of devel, so I expect the page would die immediately if we remove the folder from there.

The tutorial rework looks good to me. @thomas-bc ready for merge? If we break the README as shown on github.com, perhaps we can change that link in a dedicated PR? or we can move the "main branch" to devel since we have a tool that pulls the correct version down.

Also, we should probably rework that readme too....
