Installation instructions update

[juk80]

Hi,
as of Jan. 2023, there are some minor imprecisions with the installation instructions:

1. Create credentials -> OAuth client ID -> Other: "Other" is not available; I used "Desktop App" and the generator script worked
2. generator script "follow the instruction": copy link to browser and authorize, copy code of "code section" in generated link and paste
   Module works great.
   Thx for the great work.

Can confirm. "Desktop App" worked for me as well.

Does not work for me! But this is the obstacle it seems that google wont let allow the access.

MMM-GoogleBirthdayProvider has not completed Google's validation procedure. The app is currently being tested, and only testers approved by the developer have access to it. If you think you should have access, please contact the developer. If you are a developer of MMM-GoogleBirthdayProvider, see the error details. Error 403: access_denied
Does anyone know what I did wrong?
