Review comment:
Since FLINK-24271 is about adding an example on how to access keys with
"non-trivial" names, how about keeping the example as simple as possible to
focus on actually showing how to do that? For example, like this:
```
// STRING: '1'
JSON_VALUE('{"a.b": "1"}', '$.[''a.b'']')
```
Please also run the docs locally and make sure that the line length of the
example doesn't cause the code block to scroll. If it does, line-break the
example (as I did in the examples above) to prevent it from scrolling.
