Normalize project_name and update schema title format in build-schema module

[Aberdur]

Issue Description

The build-schema module requires two related fixes to ensure consistent and valid schema naming.
Currently, the project_name obtained from relecov_tools.utils.get_package_name() may contain spaces, and the generated schema title does not follow the expected naming convention.

Required Changes

1. Normalize project_name:

   • Add a validation step to ensure that project_name = relecov_tools.utils.get_package_name() does not contain spaces.
   • If spaces are present, they must be replaced with hyphens (-).

2. Update schema title format:

   • Change the schema title generation logic from:

     new_schema["title"] = f"{project_name} Schema."

     to:

     new_schema["title"] = f"{project_name}-schema"
