fix(doc): Maximize link points to children or shorthand example

[miroslavstastny]

Docs - Maximize button

Maximize button for an example in docs was always linked to children API. It was not possible to maximize shorthand example, maximize failed with 404 for examples which have shorthand impl only.

Now it links to the implementation (shorthand or children API) which is currently displayed.

TODO

• Update the CHANGELOG.md

just for the sake of eliminating this a bit confusing expression (in a sense that it is not immediately evident what is the difference between these two), we could use

<ComponentControls
  ...
  examplePath = {this.sourceCodeMgr.currentPath}
  ... />

and eliminate currentExamplePath from all places - as this.sourceCodeMgr already serves as state manager, and state updates are called on path change
