Simplify nextflow_schema.json title to just pipeline name

[ewels]

Summary

• Remove " pipeline parameters" suffix from the nextflow_schema.json title attribute

Changes

• Updated schema validation in schema.py to expect just the pipeline name
• Updated lint documentation examples in schema_lint.py
• Updated test assertions in test_schema.py

Why? These are the pipeline parameters after all.

[ewels]

I think it should be the pipeline title, not the title of the file.

(a) I think it's a bit self-evident and uninformative, and (b) we will likely extend this schema file in the near(ish) future to include other pipeline information that isn't just parameters.

switched the target branch to try to keep template updates out of the dev branch for a patch release.
