use wkhtmltopdf from os supplied base apt source

[sanderkwantes]

This fix ensures that odoo does not depend on an amd64 image. Apple Silicon M1 developers in particular are going to be happy about this. Docker containers are now created from an arm64 image for Apple Silicon Docker for Mac users. This eliminates the use of the more inefficient 'platform: linux/amd64' workaround.

The default included version of wkhtmltopdf in debian buster is in line with Odoo's recommended version: https://packages.debian.org/buster/wkhtmltopdf

+1 from my side for the arm64 image. However, obviously, the images are built and pushed manually to the docker hub?

Maybe we consider using Github Actions here for automatic build and push?

I'm sorry to say that it will not work. The only supported wkhtmltopdf version is 0.12.5-1.

@d-fence it works same. We use 0.12.6 for 2 years now.
