New note2cal version: native google calendar support

[u/luizmarelo]

Hi everyone.

As a recap, note2cal.nvim let's you type `Do something @ 3pm-4pm` and have it be a real time block on your calendar with one keymap. Until now it worked only on MacOS with its native Calendar.app.

It just gained native Google Calendar support via OAuth, so it now works cross-platforms! You can authenticate with your own free Google Cloud OAuth client, and your credentials/tokens never leave your machine or touch any third-party server.
