nf-core schema build uses old schema in json file

[SimonDMurray]

Description of the bug

When building a nextflow_schema.json with the command nf-core schema build the produced .json file has the line:
"$schema": "http://json-schema.org/draft-07/schema", which causes a pipeline using nf-schema to fail.
The line should be:
"$schema":"https://json-schema.org/draft/2020-12/schema",

Command used and terminal output

Command line error:
root@f90c924640fe:/# nextflow run main.nf 

 N E X T F L O W   ~  version 24.04.2

ERROR ~ Failed to load the meta schema:
    The used schema draft (http://json-schema.org/draft-07/schema) is not correct, please use "https://json-schema.org/draft/2020-12/schema" instead.
        - If you are a pipeline developer, check our migration guide for more information: https://nextflow-io.github.io/nf-schema/latest/migration_guide/
        - If you are a pipeline user, pin the previous version of the plugin (1.1.3) to avoid this error: https://www.nextflow.io/docs/latest/plugins.html#using-plugins, i.e. set `plugins {
    id '[email protected]'
}` in your `nextflow.config` file

Hi @SimonDMurray, thanks for reporting this!
It is a known issue. We are tracking all the work that has to be done related to the schema with #2429
