Fix guides of `newapp` (confusing in v5)

[islent]

I was following the guides in https://genieframework.com/docs/genie/tutorials/Developing-Web-Services.html. However, I cannot find newapp family of function in Genie@v5. They does not exist in the source code of Genie, either:

In the end, I found that newapp might be migrated to Genie.Generator (https://github.com/GenieFramework/Genie.jl/pull/519) and found them there in. It would be better to mention such changes in the tutorial.

Found the instructions in the doc: https://genieframework.github.io/Genie.jl/dev/guides/Migrating_from_v4_to_v5.html#.-Genie.new-family-of-functions

I think that v5 should be metioned in the tutorials, because new users are installing v5 by default: https://genieframework.com/docs/genie/tutorials

[essenciary]

@islent I understand, but those are the guides for Genie 4 and are correct for that version of Genie. The docs now include links to both versions of Genie, see here https://genieframework.com/docs/. How did you get to that page?

I think we need to improve the docs to make it visible on each page the version (and if it's not the docs for the latest version).

From a chrome bookmark added a couple of months ago :D

Yes, that is a solution!
