Visiting https://beta-galaxy.ansible.com/geerlingguy/docker takes you to a page with a bunch of docker named roles, but not the geerlingguy one.

Under the covers, the UI is requesting https://beta-galaxy.ansible.com/api/v1/roles/?username=geerlingguy&name=docker which doesn't work because the backend doesn't look for "username".

Per the core cli requirements, the backend will allow for github_user as a filter, which does return the correct single result ...

https://beta-galaxy.ansible.com/api/v1/roles/?github_user=geerlingguy&name=docker

We can do one of the following:
A) fix the ui to use github_user instead
B) add support for the username parameter in the backend
