Update PR guidelines to expand on project related news
Let's update our PR guidelines located here: https://www.eclipse.org/org/press-release/pressrelease_guidelines.php
*** Update text to include "adoption news" as an example of milestone under the Project Oriented Press Release section. That first paragraph should now read:
Project Oriented Press Releases
Press releases to announce news about a project, (e.g. a new version or significant milestone such as industry adoption news) are issued by the Eclipse Foundation. All projects are invited to propose potential press releases. The Project/PMC Lead is required to approve any project-specific press release and act as a spokesperson for the release. To encourage a vendor neutral community, companies are encouraged to not issue press releases regarding a specific Eclipse project.
