fix(react): assert test property is defined on webpack rule in nx-react-webpack-plugin (#27525)
The `removeSvgLoaderIfPresent` method in `apply-react-config.ts`
iterates through each Webpack rule, calls `toString` on each `test`
property, and checks for the presence of the string `"svg"` to see if
any existing SVG plugins need to be removed.

Some of the Webpack rules in the config don't have the test property,
and calling `toString` without asserting the test property is defined
first throws type errors.

This commit introduces a very small change that simply asserts that
`rule.test` is not `undefined` before calling `.toString()`.

## Current Behavior
Running a React Webpack library with `svgr` enabled causes compilation
errors.

## Expected Behavior
Enabling SVGR in the `NxReactWebpackPlugin` config should compile as
normal.
