fix(repo): fix e2e CI failures from Node 22.12 incompatibility (#34501)

## Current Behavior

Two categories of e2e CI failures were observed in run
https://github.com/nrwl/nx/actions/runs/22127884259:

1. **`e2e-nx-init` and `e2e-js` fail on Node 22.12.0** with:
   ```
error eslint-visitor-keys@5.0.0: The engine "node" is incompatible with
this module.
   Expected version "^20.19.0 || ^22.13.0 || >=24". Got "22.12.0"
   ```
Node 22.12.0 is one minor version short of the `^22.13.0` range required
by `eslint-visitor-keys@5.0.0`.

2. **`e2e-nx` tests fail because `[isolated-plugin]` / `[plugin-worker]`
verbose messages leak into captured stdout**, causing:
- `JSON.parse(runCLI('show project --json'))` to throw `SyntaxError:
Unexpected token 'i', "[isolated-p"...`
- `expect(runCLI('show projects')).toEqual('')` to fail with worker
spawn noise
- The `@nx/workspace:infer-targets` test to unexpectedly find
`@nx/remix` in output (from a worker spawn message)

Root cause: in `isolated-plugin.ts`, the plugin worker's stdout was
piped directly to `process.stdout`, so `[plugin-worker]` verbose
messages written by the worker ended up in the stdout captured by
`runCLI` in e2e tests.

## Expected Behavior

1. The CI matrix uses a Node 22.x version that satisfies `^22.13.0`.

2. Plugin worker verbose/diagnostic messages go to `process.stderr` (not
`process.stdout`), so they don't contaminate output captured by `runCLI`
in e2e tests. Both worker stdout and stderr now pipe to
`process.stderr`, and the max listener bump is consolidated to `+2` on
stderr.
