fix(deps)!: Upgrade node/npm engine spec

The engine spec applied here matches the minimum requirements of all transient dependencies (in `package-lock.json`). The engine requirement is changed from `npm` version to `node` version to better match with the engine spec discovered as outlined in the install attempts below (nobody seems to depend on npm versions, only node version).

With `engine-strict=true` in `.npmrc`, I attempted to install with old versions of node/npm, until successfully installed and tested.

Minimum spec install attempt #1:
```
$ nvm install v18.1.0
v18.1.0 is already installed.
Now using node v18.1.0 (npm v8.8.0)
$ npm install
npm ERR! code EBADENGINE

npm ERR! notsup Required: {"node":">=20.8.1"}
npm ERR! notsup Actual:   {"npm":"8.8.0","node":"v18.1.0"}
```

Minimum spec install attempt #2:
```
$ nvm install v20.8.1
v20.8.1 is already installed.
Now using node v20.8.1 (npm v10.1.0)
$ npm install
npm ERR! code EBADENGINE
npm ERR! engine Unsupported engine
npm ERR! engine Not compatible with your version of node/npm: eslint-visitor-keys@4.0.0

npm ERR! notsup Actual:   {"npm":"10.1.0","node":"v20.8.1"}
```

Minimum spec install attempt #3:
```
$ nvm install v20.9.0
v20.9.0 is already installed.
Now using node v20.9.0 (npm v10.1.0)
$ npm install
