[Feature Request] Better project template configuration options

[bavalpey]

I really like hatch. In fact, I've been using it a lot. However, the one area where hatch is weakest is in project templates. We have almost no ability to modify how project templates are created (or at least, none documented). The documentation for the configuration options is lacking, and the blogposts don't seem to be paying any attention to it, either.

First, licenses should be always put in the LICENSES/ directory regardless if there is more than one license. This is in accordance with the REUSE spec. If there is one license, it is fine to have it in the project root as well, but the creation of the LICENSES directory should not be conditional.

Second, there is currently no way to adjust the copyright text in headers. For instance, it always uses the author for the copyright text. This is insufficient for a good percentage of projects, where the author is different from the copyright holder (e.g., where work done is copyrighted by the company and not the author).

Third, is there support for defining arbitrary project template structures? What if I want to add, say, a .editorconfig to the project root. Or maybe I want a default .gitignore, or to change the placeholder text in README.md. If there are ways of doing this already, they are not communicated to the user.
