[CHORE] The walkthrough appears to be outdated (v1.6.14)

[LuchoTurtle]

As of the time of writing, Phoenix's latest version is 1.6.14 (with 1.7 apparently coming very soon 🤩 ).
This tutorial is great and works perfectly if I clone and run it.

However, when I try to build a new Phoenix app from scratch and follow this tutorial,
some information appears to be outdated.

Here are a few examples:

• The boostrapped project with the newest version appears to have more files in some folders, namely lib\templates\layout.
• Updating the layout template on app.html.eex does not make sense now, since the information is on root.html.eex.
• Tests do not pass after "correcting" in page_controller_test.exs.

This is a snowball effect and for anyone that is new, they expect this tutorial to "Just Work^TM".
No doubt it does with v.1.6.11, though!

I'll try to update the tutorial to the latest version and the README file accordingly to the best of my abilities 😄 ...

Todo

• clone the repo to localhost ⬇️
• make a reference copy of the repo e.g. cp phoenix-chat-example phoenix-chat-example_OLD so that you can have one open while editing the other and not have to switch between branches. ✌️

Note: this is where having that second or third screen comes into play. 💻 + 🖥️ + 🖥️ 💭

• Create a new branch e.g. rewrite-phoenix-v1.6.14-issue#112 (snappy name, right? 😜)
  • git push the new branch to GitHub ASAP so that you can see if CI (GitHub Actions) continues to pass.
• Re-create the app from scratch following the instructions in the README.md as much as possible. 🧑‍💻
• Update the sections that require it. 🆙
• Preserve the Testing and any other sections that are still relevant. 🥇
• Create a PR and assign it to me for review. 🙏

@LuchoTurtle thank you very much for opening this issue. 🎉
I periodically go through the tutorials with the latest version of Phoenix and make adjustments. 📝
But I haven't done it properly for a few versions ... ⏳ 🙄

Sounds like we need to treat the existing code as a reference
and essentially re-do it from scratch with a full mix phx.new ...

That being the case, I've updated the OP to reflect the work that needs to be done. 💭

@nelsonic consider changing the description to 💬 A Step-by-Step Beginners Tutorial for Building, Testing & Deploying a Chat app in Phoenix 1.6.14🚀 😉
