jcenter URL is now https

[Robert C. Kahlert]

Hi, Since January 2020, the bintray specification needs an HTTPS URL, not an HTTP URL, as your Maven example specifies.
<repositories> <repository> <id>central</id> <name>bintray</name> <url>https://jcenter.bintray.com</url> </repository> </repositories>
Hope that helps :)

Hey, @canonicalchris! Thanks. I can fix it, or do you want to raise a PR?

PR is pull-request?

[Sergey Tselovalnikov]

Yep, a pull request :)
