Include artifact coordinates in documentation

[boerngen-schmidt]

Hello,

currently I found it quite a hassle to find the atrifact coodinates to use with maven or gradle.
It would be great if you could include a brief maven configuration like https://github.com/spring-projects/spring-data-mongodb#maven-configuration

Otherwise thanks for your awesome work.

Thanks for the request @boerngen-schmidt.

This will be covered in gh-499 in the section "Getting Started -> Installing Spring Authorization Server".

I'll close this as a duplicate.
