Make it compile on Elixir 1.15

[haljin]

Since Elixir 1.15 introduces code path pruning this library cannot compile anymore without the :private_key application in extra_application.

[haljin]

Is this library still maintained? :(

[ahovgaard]

Shouldn't it be :public_key?

Suggested change

	extra_applications: [:logger, :private_key]
	extra_applications: [:logger, :public_key]

I'm not seeing this fix in the current easy_ssl release version: "1.3.0",

defp deps do
    [
      {:easy_ssl, "~> 1.3"},
    ]
  end

mix deps.get && mix deps.compile resulted in:

==> easy_ssl
Compiling 1 file (.ex)

== Compilation error in file lib/easy_ssl.ex ==

But as soon as I added :public_key to my deps/easy_ssl/mix.exs file it compiled with no problem:

==> easy_ssl
Compiling 1 file (.ex)
Generated easy_ssl app

I'm on Ubuntu 22.04.4 LTS and had the same issue with elixir via apt and via asdf.

So I guess there is a merge conflict for this branch maybe?
