[FEATURE] Use https://reuse.software/

[ypid-geberit]

Is your feature request related to a problem?

Apache-2.0 is chosen for the user. This choice should be explicit. Additionally this choice should be machine readable and linted.

Describe the solution you'd like

Integrate https://reuse.software/. As this is a template, this means two things:

1. Make the template itself comply with https://reuse.software/.
2. Help the user to make a license choice and make the converted project comply with https://reuse.software/.

Describe alternatives you've considered

Additional context

It seems the copyright framework was put together 2014. Now that https://reuse.software/ exists I think this can be reconsidered.

The question is also how the template itself should/is licensed and what that means for derived projects? Is the assumption that this "skeleton" is in itself not copyrightable? I guess not as you have a LICENSE file. But than I start of with Apache-2.0 license.
