When adding a repository as an admin, and choosing Bitbucket as a
hosting service, an incorrect repository name description displays.
In the "Repository Name" description, when using the "Personal"
repository plan, the description would read "The username of the
user who owns the repository. This is the <repo_name> in<username>/<repo_name>/". This isn't correct.

It now reads "The name of the repository. This is the <repo_name> in<username>/<repo_name>/".

Tested by refreshing the page, and confirmed that the "Repository
Name" description is the new description. Also, navigated to
http://localhost:8080/admin/, clicked on "Add +" under Repositories,
and confirmed that on
http://localhost:8080/admin/db/scmtools/repository/add/ the
description text has changed.

No other description fields have changed.
