Dependency issues prevent installation on Windows; consider splitting recipe into multiple outputs

### Solution to issue cannot be found in the documentation.

### Issue

Looking at the [upstream repo](https://github.com/omni-us/jsonargparse/blob/v4.32.0/pyproject.toml), the only core dependency of the `jsonargparse` package is `PyYAML>=3.13`. Therefore, this should be the only dependency for this base package on conda-forge.

Currently, this conda-forge package requires many other dependencies, some of which (but not all) are optional extra dependencies of the upstream package. The particular dependency which caught my attention is the dependency on `jsonnet`, which cannot be installed on Windows.

If desired, the recipe can generate multiple outputs which correspond to the optional extra dependencies of this package, as with [this recipe](https://github.com/conda-forge/pypdf-feedstock/blob/main/recipe/meta.yaml).
