Lint pipelines nextflow schema against the meta schema

[mirpedrol]

Description of feature

Lint pipelines parameters schema (nextflow_schema.json) against the meta schema

To lint all pipelines, we should work on these steps:

• Manual check of the meta schema to check we're not missing anything obvious
• Think about hosting a copy of the meta schema somewhere else (currently under the nf-schema repo)
• Test all / most nf-core pipelines locally to check for errors
• Write GitHub action CI for one or two pipelines
• Add CI to the template
