fix: refined Promise detection logic to account for alternate implementations

[emeraldsanto]

Description

This PR aims to fix bugs when using this library with third-party modules which either wrap the native Promise object or declare alternative implementations altogether. Due to the way we currently handle Promise detection, the latter case would fail that check and be treated as a synchronous value and unexpectedly throw instead of being handled by doublet.
