[Task]: add a list of common used methods that can be accessed in the script transform

### What needs to happen?

In the Script transform we mention that we bind the current transform context.
Users do not know what you can do with this, add some examples such as `transform.resolve('${PRM_TEST}')` and other useful methods that can be accessed.
