Allow the usage of JSON for Elixir 1.18+

@altjohndev I couldn't force push to your branch, but this is your PR with some changes I made on top of it to remove the compile-time configuration and other small cleanups. Can you review this? 🙃

LGTM, thanks for applying the changes!

The CI is failing for Elixir 1.18+. Maybe test/support/*can be ignored for Dialyzer?

Given that we're introducing a shim under Sentry.JSON shouldn't we also raise Sentry.JSON.DecodeError?

We're not introducing Sentry.JSON for users, it's just for us during this transition time.

Just FYI:

iex(2)> Sentry.JSON.encode(%{"dates" => %{Date.utc_today => 1}}, JSON)
{:error,
 %FunctionClauseError{
   module: :elixir_json,
   function: :key,
   arity: 2,
   kind: nil,
   args: nil,
   clauses: nil
 }}
 
iex(3)> Sentry.JSON.encode(%{"dates" => %{Date.utc_today => 1}}, Jason)
{:ok, "{\"dates\":{\"2025-03-02\":1}}"}
