Enh: Support dependency groups in our pyproject.toml / template

[lwasser]

Currently we are defining sets of development tools within each hatch environment. This is great BUT it pins the user to hatch more than if we used the new pep standard that defined development groups!

Development groups are now supported in the recent version of hatch so we should do the following

1. move all dependencies to development groups
2. Update the hatch environments to use these groups in the associated environments
3. Update the documentation that we did that!

i think I found your comment:

pyos-package-template/template/pyproject.toml.jinja

Line 72 in c77ad63

[project.optional-dependencies]

i'll look into this.

for (2) - is that a change to the root pyproject or the same templated one?
