feat(core): add packageManager field when setting up new workspaces

[juristr]

Current Behavior

Currently we don't add the packageManager property when generating a new workspace.

Expected Behavior

We should have it as more and more tooling relies on it to make decisions. (e.g. on CI etc..)

@juristr I think we'll want a custom snapshot serializer for these otherwise they will be subject to change every time our CI environment changes by even a patch version of npm

@JamesHenry oh yeah good catch

Nx Cloud is proposing a fix for your failed CI:

These changes fix the e2e test failures by ensuring the generated test specs use npm commands that match the package manager configured in the created workspaces. Since the create-package template hardcodes packageManager: 'npm' in the generated workspace, the e2e tests now correctly use npm ls and npx instead of dynamically resolved commands from the generating workspace (which uses pnpm).

We could not verify this fix.
