Mixed Contribution Guidelines with Collaborator Guide #5413
Description
Right now the Collaborator Guide has duplication or mixed content with the Contribution Guide
For example, the Collaborator Guide has a "Code Editing" section referring to Adding new Pages and Translations, yet, the Contribution Guide has sections for "Creating Components", "Adding Storybooks," and "Creating Unit Tests". (https://github.com/nodejs/nodejs.org/blob/main/CONTRIBUTING.md#creating-components)
Since the CONTRIBUTING.md is also a top-level bylaw document for the Website Team, we should move all these "collaborating"-specific snippets and sections from CONTRIBUTING.md to COLLABORATOR_GUIDE.
And the Collaborator Guide should be mentioned at the top of the CONTRIBUTING guidelines as the reference for standards for making code changes.
