poetry-core 2.0.1: man pages not installed any longer

[0-wiz-0]

When building a wheel for beets 2.2.0 with poetry-core 2.0.1, the man pages are not included any longer.

# python3.13 -m build --wheel                                                                                                                                                                                     * Creating isolated environment: venv+pip...
* Installing packages in isolated environment:
  - poetry-core>=1.0.0
* Getting build dependencies for wheel...
* Building wheel...
Successfully built beets-2.2.0-py3-none-any.whl
# tar tvzf dist/beets-2.2.0-py3-none-any.whl |grep man/
#

Compare to when I add ,<2 to the dependency line in pyproject.toml:

# python3.13 -m build --wheel
* Creating isolated environment: venv+pip...
* Installing packages in isolated environment:
  - poetry-core>=1.0.0,<2
* Getting build dependencies for wheel...

This is correct and happens because poetry-core since version 2.0 changed how the default include works. It now matches the behavior that was set up in this commit, that is, defaults to including only in sdists, not in wheels.

It is generally recommended to pin your build backend requirement to a range between major versions, poetry-core>1.0,<2 for version 1.x and poetry-core>2.0.1,<3 for version 2.x.

I think installing man pages for binaries is a good idea. So I'd like to leave this as a change request so that the man pages will still be installed with poetry-core 2.0.1.
