Including this lesson on the new community lessons page

[ErinBecker]

@fmichonneau has updated the lesson template to enable support of Incubator lessons!

This update:

• Creates a top-of-page banner to indicate that this lesson is in the incubator (and not an official Carpentries lesson). This banner is in addition to the existing "lesson life cycle" banner that appears on some official Carpentries lessons (for example the geospatial lessons) to indicate whether lessons are pre-alpha, alpha, beta, or stable.

• Changes the license information to make it clear the copyright is not held by The Carpentries or any of its lesson programs.

• Replaces The Carpentries (or SWC/DC/LC) logo in the upper left hand corner of the template with The Carpentries Incubator logo.

@fmichonneau and I are happy to do the heavy lifting of bringing this template into your lesson repository (or helping you with the logistics if you'd like to try it yourself). Once this has been done, your lesson will appear on a "Community Contributed Lessons" page on The Carpentries website!

Please respond to this issue to let us know if you approve these changes. Please also indicate whether you would prefer to pull in the template update yourself, or would prefer @fmichonneau and I to take the lead on that. Looking forward to posting your lesson publically and getting the word out about this awesome resource!
