Add basic support for Workflow Test Files '*-test.yml'

[davelopez]

This PR adds a new workflow-tests-language-service package with a basic implementation of a language service for Galaxy workflow tests definition files.

It also includes a big refactoring using a new IoC container approach based on Inversify and much more test coverage.

The schema definition for workflow test files is still experimental (galaxyproject/galaxy#17128) but good enough to be very useful already (thanks to @mvdbeek).

Features:

• YAML syntax coloring and validation
• Schema support
  • Schema-based help tooltips
    
  • Basic schema-based auto-completion
    
  • Basic schema-based validation
    
• Associated WF file support
  Given the following associated workflow:

  class: GalaxyWorkflow
  doc: ""
  inputs:
    the_input:
      type: File
      doc: This is the documentation for the input parameter.
    a collection:
      type: Collection
      collection_type: list
  outputs:
    the_output:
      outputSource: cat1/out_file
  steps:
    cat:
      tool_id: cat1
      doc: ""
      in:
        input1: the_input
