Evaluate uv as replacement for poetry

[dalito]

@markdoerr - This is for you 😄 .

Getting "uv-ready" was part of my motivation for doing the poetry-1.x to poetry-2.x PRs for linkml-project-cookiecutter and linkml-runtime. Here we could experiment without disturbing many users since the template is new and has only few users (mainly pid4cat-model).

The conversion to uv should be straight forward. The only unknown is how to replace the poetry plugin poetry-dynamic-versioning.
