Facilitating Phoenix upgrade process

Usually, when I upgrade apps to newer versions of Phoenix, I regenerate the app to ensure I get all the goodies.
Dealing with dependencies is one of the worst parts, but I make it easier by separating Phoenix from the app dependencies.

def project do
  [
    # ...
    deps: phoenix_deps() ++ app_deps(),
  ]
end

defp app_deps do
  [
    # ...
  ]
end

defp phoenix_deps do
  [
    {:phoenix, "~> 1.7.14"},
    {:phoenix_ecto, "~> 4.5"},
    {:ecto_sql, "~> 3.10"},
    # ...
  ]
end

Then it’s easier to check the difference using git.
