fix(cli, dev-server): add `SYSTEMROOT` for `open` when opening browsers on Windows (#23287)

# Why

Fixes #23252

# How

- `open` has a bug on Windows, where it [uses
`process.env.SYSTEMROOT`](https://github.com/sindresorhus/open/blob/main/index.js#L173)
instead of
[`process.env.SystemRoot`](https://en.wikipedia.org/wiki/Environment_variable#:~:text=The%20%25SystemRoot%25%20variable%20is%20a,including%20the%20drive%20and%20path.)
- This causes the executed command to run with `undefined\\...`
- There has been no fix yet, and due to `open` being fully ESM now, we
probably can't upgrade too

This basically sets the missing `SYSTEMROOT` when trying to open a
browser on Windows. It's fixed in both `@expo/cli` as well as
`@expo/dev-server` (to open the Chrome DevTools).

# Test Plan

This has to be tested on Windows.

- `$ yarn create expo ./test-browser -t tabs@beta`
- `$ cd ./test-browser`
- `$ yarn start`
- Try pressing the following keys:
- `j` -> to open the Chrome DevTools, after connecting a device. Should
work as expected.
- `w` -> to open the browser with Metro web. Should work as expected.
