create_parameter_json_from_nfcore_schema.py - issue

Firstly, thank you for the useful script.

[create_parameter_json_from_nfcore_schema.py](https://github.com/aws-samples/amazon-omics-tutorials/blob/main/utils/scripts/create_parameter_json_from_nfcore_schema.py)

Using this script with the latest version of the schema in nf-core/sarek creates requirements that currently prevent registration with AWS HealthOmics.

https://github.com/nf-core/sarek/blob/3.4.2/nextflow_schema.json

The following specifications are currently not allowed in AWS HealthOmics. So it seems like we need something to either check this as an error or guide us to fix it.

Start with utils/scripts/create_parameter_json_from_nfcore_schema.py and compare its output for nf-core/sarek 3.4.2 with the AWS HealthOmics create-workflow validation errors. Check how descriptions are transformed, then verify that the generated nextflow-sarek-parameter.json satisfies the reported length and character constraints when used with the shown AWS CLI command.
