docs(configuration): Clarify use of paths in Condition (#5302)

* Clarify use of paths in Condition

Due to path.resolve not adding a trailing slash automatically, building a Condition using it might apply to more than the user expects. Modified the example slightly and added some comments to it.

* Break comments to better fit page layout

* Use path.join instead of path.resolve
