Change Request: Replace `npm-run-all2` with a native script to reduce the dependency footprint

[lumirlumir]

Which packages would you like to change?

• espree
• eslint-scope
• eslint-visitor-keys

What problem do you want to solve?

In this issue, I would like to suggest replacing the npm-run-all2 package with a native script to reduce the dependency footprint.

Currently, the npm-run-all2 package is only used in the espree package as a devDependency, and it is only used when running the test scripts test:cjs and test:esm.

What do you think is the correct solution?

The npm-run-all script can be simply replaced with a native script:

- "npm-run-all -s test:*"
+ "npm run test:cjs && npm run test:esm"

Also, eslint-visitor-keys follows this strategy:
https://github.com/eslint/js/blob/main/packages/eslint-visitor-keys/package.json#L51

We generally don't care too much about dev dependencies as they only affect the team and not end users. If you'd like to swap it out, you're welcome to, I just don't know that it's worth the time.
