chore(examples): bumps custom components example to latest and runs seed on init (#10661)

The custom components example no longer ran seed on init. This is done
through a preconfigured migration script that automatically runs on
startup. The `@payloadcms/graphql` package was also incorrectly
installed as a dev dependency and the lockfile was significantly out of
date. The `react` and `react-dom` packages were also pinned to v19.0.0,
with their corresponding types packages to v19.0.1. These now all match
as expected and are identified using the caret operator to ensure the
latest versions are installed.
