Remove the `experimental.instrumentationHook` option from the generated
`next.config.mjs` template, as it is no longer needed in newer versions
of Next.js. Bump package version from 1.3.1 to 1.3.2.
Remove the screenshot image link from the generated README.md
template as it references a non-existent asset path that would
cause broken image links in new projects. Bump version to 1.3.1.
