Update webpack docs when using SVGR and asset SVG in the same project

[smol-honk]

Summary

When trying to use webpack 5's resourceQuery as defined in the previous docs, I kept getting a base64 string of the compiled react component not the svg.

This ended up erroring out all usage of import svg from 'my-svg.svg?url since it wasn't actually a base64 of the xml svg. I updated the docs with the fix I used to only have the svgr loader called when the resourceQuery is not url.

Also updated the.gitignore to ignore MacOS specific files in the future.

Test plan

The examples/webpack didn't use the resourceQuery option so the only edits were made to the documentation text. I ran the gatsby doc app locally to check that it works and reflected the change in the right spot and then linted/tested the entire repo.
