Remove curl dependency

[ivanychev]

Thanks for the amazing GitHub Action!

This PR removes curl usage from the script and replaces it with python3. Many hosted GitHub Action runners don't have curl by default, so they are required to install it before using this action. This PR ensures that the installation of curl is not needed.

Cool. I agree, cutting dependencies is good, but would you mind showing me documentation that python3 always needs to be present in self-hosted runners? Otherwise, aren't we just substituting one dependency for another?

Hey @sondrelg! The script already relies on Python 3 to install poetry (search for python3 in the file). The script uses the “official” way of installing poetry: (https://python-poetry.org/docs/#installing-with-the-official-installer) — it downloads Python script and executes it.

Hehe yeah good point. I'll try to get this reviewed properly this week 👍
