don't use 22.18.0 for now

[rsese]

Why:

fixes: https://github.com/github/docs-engineering/issues/5623
related? nodejs/node#59364

seeeems like a node problem with 22.18.0? only a problem in github/docs right now because in docs-internal i see node 22.14.0 getting installed during setup (I assume because different runners?)

my local testing with 22.17.0 vs. 22.18.0:

➜  docs git:(main) nvm use 22.17.0
Now using node v22.17.0 (npm v10.9.2)
➜  docs git:(main) npm run playwright-test -- src/fixtures/tests/playwright-local-dev.spec.ts:37 

> playwright-test
> playwright test --config src/fixtures/playwright.config.ts --project="Google Chrome" src/fixtures/tests/playwright-local-dev.spec.ts:37


Running 1 test using 1 worker

  ✓  1 [Google Chrome] › src/fixtures/tests/playwright-local-dev.spec.ts:37:1 › search "foo" and get results (1.9s)
[WebServer] (node:29205) [DEP0060] DeprecationWarning: The `util._extend` API is deprecated. Please use Object.assign() instead.

➜  docs git:(main) nvm use 22.18.0                                                               
Now using node v22.18.0 (npm v10.9.3)
➜  docs git:(main) npm run playwright-test -- src/fixtures/tests/playwright-local-dev.spec.ts:37 

> playwright-test
> playwright test --config src/fixtures/playwright.config.ts --project="Google Chrome" src/fixtures/tests/playwright-local-dev.spec.ts:37

SyntaxError: The requested module '@playwright/test' does not provide an export named 'Page'
Error: No tests found.
Make sure that arguments are regular expressions matching test files.
You may need to escape symbols like "$" or "*" and quote the arguments.

so same error as https://github.com/github/docs-internal/actions/runs/16891261375/job/47851347313

What's being changed (if available, include any code snippets, screenshots, or gifs):

• update engines to not use 22.18.0 temporarily

I think this engines syntax works and our setup action will use it? if there's a better way to do it let me know!

Pull Request Overview

This PR temporarily restricts Node.js version 22.18.0 due to a compatibility issue with Playwright tests. The change modifies the engines field in package.json to exclude the problematic version while maintaining support for Node.js 20.x and earlier 22.x versions.

• Excludes Node.js 22.18.0 from supported versions to resolve Playwright test failures
• Maintains compatibility with Node.js 20.x and Node.js 22.0.0 through 22.17.x
