Disable the `NativeImageDecoder` in the `node/pdf2svg.js` example (issue 7901)
Disable the `NativeImageDecoder` in the `node/pdf2svg.js` example (issue 7901)

It doesn't really make sense to attempt to utilize the `NativeImageDecoder` in Node, since there's no native image support available, hence building on PR 8035 we can easily disable it in the example.

Fixes 7901.
