Fix init command in monorepo

[frandiox]

Sometimes when creating new projects with h2 init in our monorepo, there's an NPM 401 error during dep intallation. This PR copies .npmrc to the new project in the monorepo to workaround this issue.

Aside from that, when choosing not to install dependencies it will do an automatic symlink to the monorepo node_modules, just like we do during testing. This is useful to create projects to test things quickly without installing deps.

We detected some changes in packages/*/package.json or packages/*/src, and there are no updates in the .changeset.
If the changes are user-facing and should cause a version bump, run npm run changeset add to track your changes and include them in the next release CHANGELOG.
If you are making simple updates to examples or documentation, you do not need to add a changeset.
