Maven bintray repo dependency requires https (README)

[dleary]

Apparently the bintray repo dependency needs to use https, not http as currently documented in the README.

Version info

• intercom-java version: 2.8.1
• Java version: 1.8.0_232

Expected behavior

Maven build with bintray dependency as declared in the README should work.

Actual behavior

http://jcenter.bintray.com url produces maven error:

[ERROR] Failed to execute goal on project ...: Failed to collect dependencies at io.intercom:intercom-java:jar:2.8.1: Failed to read artifact descriptor for io.intercom:intercom-java:jar:2.8.1: Could not transfer artifact io.intercom:intercom-java:pom:2.8.1 from/to jcenter (http://jcenter.bintray.com): Access denied to: http://jcenter.bintray.com/io/intercom/intercom-java/2.8.1/intercom-java-2.8.1.pom , ReasonPhrase:Forbidden. -> [Help 1]

Changing http://jcenter.bintray.com to https://jcenter.bintray.com yields success.

Steps to reproduce

1. Declare maven dependency per the README
2. maven compile
