docs: co-locate JS examples with JS API documentation in stats/base/dists/gamma/logcdf

Moved the JS `## Examples` section to sit between the JS `## Usage`
section and the `## C APIs` section, matching the namespace majority
ordering (10/14 siblings) and addressing review feedback that JS
examples should be co-located with the documentation for the JS APIs
rather than placed after the C interface documentation.

No content changes; section ordering only.
