Fix hex ecosystem update

[thiagogsr]

What are you trying to accomplish?

This version includes a fix that's currently breaking Dependabot in some Phoenix projects:

hexpm/hex@eca807d

The issue is when Dependabot runs mix hex.outdated, it throws an error:

** (ArgumentError) The module Phoenix.CodeReloader was given as a child to a supervisor but it does not exist

This is the related to: elixir-lang/elixir#14570

Release: https://github.com/hexpm/hex/releases/tag/v2.2.2

Anything you want to highlight for special attention from reviewers?

I had to update elixir from 1.18.1 to 1.18.4 to get this Hex version.

How will you know you've accomplished your goal?
