Add Svgr Webpack If Used

Add @svgr/webpack If Used

Adds @svgr/webpack to the workspace when a next config references it.

@svgr/webpack is no longer a dependency of @nx/next, so workspaces whose next configs resolve it - which is what the Nx 22 add-svgr-to-next-config migration inlined - must declare it themselves. This migration backfills it for those workspaces. Workspaces that already have @svgr/webpack are left untouched.

Examples

Before

{
  "devDependencies": {
    "@nx/next": "23.1.0",
  },
}

After

{
  "devDependencies": {
    "@nx/next": "23.1.0",
    "@svgr/webpack": "^8.0.1",
  },
}
