Fix dialyzer reporting unmatched_return for Sentry.PlugCapture

[maxwowo]

This issue is similar to #436. Basically the return type of Sentry.capture_message/2 is {:ok, Task.t() | String.t() | pid()} | {:error, any()} | :unsampled | :excluded | :ignored which is not handled, causing Dialyzer to complain about unmatched returns. Adding a _ = as was done in the aforementioned PR silenced it. My Dialyzer configuration is below in case it's of any interest.

dialyzer: [
  flags: [
    :unmatched_returns,
    :error_handling,
    :race_conditions,
    :no_opaque,
    :underspecs
  ],
  plt_file: {:no_warn, "priv/plts/dialyzer.plt"}
],

@mitchellhenke This PR did not make into a published version yet.

Any ideia when we can have a new version?
