Add w3curie type and edit def of curie to be less restrictive

[ialarmedalien]

Adding in the new w3curie type.

I tried to update the repo to use py3.12 with the current versions of linkml, linkml-runtime, and pyyaml so that I could regenerate the project files. Run make gen-project gave the following output:

# for all the files in the schema folder, run the gen-python command and output the result to the top
# level of the project.  In other repos, we'd include mergeimports=True, but we don't do that with
# linkml-model.
ValueError:  Unknown argument: slot_usage = {'dimensions': {'equals_number': 1}}
ValueError:  type "any_number" must declare a type base or parent (typeof)
cp staging/*.py linkml_model
poetry run gen-project -d staging --config-file gen_project_config.yaml linkml_model/model/schema/meta.yaml
Traceback (most recent call last):
[...snip a load of callback lines...]
ValueError: The ifabsent value `default_range` of the `range` slot could not be processed
make: *** [gen-project] Error 1

Looks like the various project generators, etc., have become more restrictive since linkml-model was last updated.

ETA: just seen the series of PRs to update the model repo. I can rebase this PR and generate the new files once the deps and other bits and pieces are fixed and merged.
