Describe the bug

In a couple of the guides in the Keycloak documentation, there are examples of how to include external jars in a customized image via the container ADD instruction. While they mention -chown, they do not mention -chmod. At least in some scenarios not setting the file mode will lead to permission errors at Keycloak startup, e.g.:

```
ERROR: Failed to open /opt/keycloak/lib/../providers/ojdbc11.jar
ERROR: /opt/keycloak/lib/../providers/ojdbc11.jar (Permission denied)
```

The documentation should be improved to include --chmod=644 for in its examples, to allow more users to have an error-free experience

Version

nightly

Regression

How to Reproduce?
