Use pixi to get information

[roaldarbol]

Currently, it doesn't write the name and email. It's because the jinja extension we're using add's a newline after the value, causing the author line in pixi.toml to be split into multiple lines. The used method was found here: https://github.com/orgs/copier-org/discussions/672.

EDIT: The real issue here is to find a way to utilize the fact that pixi can get some information, e.g. platform and git info. Might need a separate action/hook after the questions.
