Fix querySerializer example

[kaechele]

Changes

The example function for the querySerializer doesn't actually do what it says it does.
The comment next to the return statement suggests the output would be ?tags[]=food&tags[]=california&tags[]=healthy, however the output of the current snippet is actually: tags[]=food,california,healthy.

Furthermore, the snippet also does not place any & characters between query parameters.

This PR fixes that, so that the output is actually ?tags[]=food&tags[]=california&tags[]=healthy (strictly, the output is actually tags[]=food&tags[]=california&tags[]=healthy but I just assumed the ? is to demonstrate how it would look like in an URL)

How to Review

Try the new snippet.

Right the intent was just to make the example more clear to people who may not instantly understand what “query” refers to in OpenAPI terminology—the search params in the URL. Not important; just meant to be sort of a hint
