Update svgo to v3.x.x

Currently when this package is installed you get a warning sth like this:
```
warning babel-plugin-inline-react-svg > svgo > stable@0.1.8: Modern JS already guarantees Array#sort() is a stable sort, so this library is deprecated. See the compatibility table on MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#browser_compatibility
```

The issue in svgo has been solved (https://github.com/svg/svgo/issues/1689), and the fix is included in [v3.0.0](https://github.com/svg/svgo/issues/1689#issuecomment-1288122399).

I don't know what breaking-changes v3 causes and how much work is needed here, but it would be nice if svgo could be updated to version >=3.0.0 to get rid of that warning (and make use of new features).

Start by locating the package dependency declaration for svgo and review the v3 release notes and migration guidance linked by the issue. Check the plugin's existing build or test entry points for compatibility, then confirm installation no longer emits the stable@0.1.8 warning and that SVG optimization still works.
