Docker readme for Confluence has the incorrect /lib directory documented for installing jdbc files

Issue Summary

The Confluence Docker page in https://hub.docker.com/r/atlassian/confluence-server/ indicates that users should be copying the downloaded mysql or oracle jdbc drivers into the

/opt/atlassian/confluence/lib

directory.
 

 docker cp mysql-connector-java.x.y.z.jar confluence:/opt/atlassian/confluence/lib
docker restart confluence

 
However this appears to be incorrect of Confluence.

Steps to Reproduce

1. Follow steps in https://hub.docker.com/r/atlassian/confluence-server/ for copying mysql jdbc jar file

Expected Results

Following the steps in the guide should let you connect to such a database.

Actual Results

Confluence still can't connect to that database when following documented steps

Workaround

copying these files to the directory

/opt/atlassian/confluence/confluence/WEB_INF/lib 

will work.
