🚀 notify cdfoundation (landscape) when 300+ github star

When the project is mature enough and match the requirements:

> - We welcome additions for CI/CD projects that clearly fit in an existing landscape category, and that have 300+ GitHub stars.
> - Put the project in the single category where it best fits.
> - We are unlikely to create a new category for projects as we'd rather find the best home with the current options.
> - Projects must be hosted on or mirrored to GitHub.
> - Your project or company needs a logo and the logo needs to include the name.
> - Crunchbase organization should be the company or organization that controls the software. That is normally the owner of the trademark, whether or not a trademark has been formally filed.
