Hi Lars,

It seems dependencies from python-xyz.scm are still required to enter
the build process for python-hatchling-bootstrap, even if hatchling does
not explicitly require them.

 (1) If we comment out the dependencies from python-xyz.scm, we get this
error:
--8<---------------cut here---------------start------------->8---
starting phase `build'
* Getting dependencies for wheel...

ERROR Missing dependencies:
	pathspec>=0.10.1
	pluggy>=1.0.0
--8<---------------cut here---------------end--------------->8---

(2) If we minimize the dependency list to the following, then
python-hatchling-bootstrap builds correctly:
--8<---------------cut here---------------start------------->8---
(inputs (list python-editables
              python-packaging-bootstrap
	      ;; Below from python-xyz.scm, can be moved to python-build.scm
	      python-pathspec-0.10.1
	      ;; Below from python-xyz.scm, can be moved to python-build.scm
	      python-pluggy-1.0
	      python-tomli))
--8<---------------cut here---------------end--------------->8---
Changing the build system to (pyproject-build-system) produces the same
results.

Since python-pluggy-1.0 and python-pathspec depend only on packages
defined in python-build.scm, I propose moving them to python-build.scm.

What do you think?
