Projects aren't "Python projects" or "JavaScript projects" but
rather "projects with Python components" and "projects with
JavaScript components." A project might have deliverables with
repositories containing implementations of things in different
languages, or may even have multiple programming languages
represented within a single deliverable repository. Make it more
clear that language-specific PTI guidance is to be followed based on
the languages which are present, rather than implying that projects
are shoe-horned into one specific language.
