Update to Phoenix v1.5.3 and LiveView v0.13.2 about phoenix-liveview-counter-tutorial

[BigTom]

End user here:

Branch seems to work fine for me (master ran but counter did not work). If that helps?

• Running on macos catalina
• Elixir 1.10.3 (compiled with Erlang/OTP 22)
• Phoenix v1.5.1
• node v14.0.0

See the upgrade guide: https://gist.github.com/chrismccord/e53e79ef8b34adf5d8122a47db44d22f

If you need to first update erlang and elixir using asdf:

• asdf update to update asdf itself
• asdf plugin list to make sure you have erlang and elixir plugins
• asdf plugin update erlang to update the erlang plugin (repeat for elixir)
• asdf install erlang latest to install the latest erlang version
• asdf global erlang <version> to set the default version of erlang
• asdf list erlang to see the list of installed versions

@SimonLab seems like it's worth adding an intro to asdf somewhere.
e.g: https://github.com/dwyl/dev-setup or https://github.com/dwyl/learn-elixir ?

If people don't have any prior experience with the tool we are introducing them to something they don't need for the tutorial which creates a barrier to entry. Not saying asdf is not a good tool, just that it's probably not necessary for this tutorial. But it's totally legit in the toolbelt of an experienced developer. 👍
