@bugsnag/electron does not work with Windows 7 and Electron 19+

Describe the bug

The os.hostname() node API throws on Windows 7 with Electron 19+ with a uv_os_gethostname returned ENOSYS error. This API is used in @bugnsag/cuid/lib/fingerprint.js, and causes a crash on startup.

• Libuv bug: https://github.com/libuv/libuv/issues/3260
• Node bug: https://github.com/nodejs/node/issues/41297
• Electron bug: https://github.com/electron/electron/issues/34404

libuv and node don’t support Windows 7, so those projects seem very unlikely address this. Electron claims support for Windows 7 but it’s unclear if they will address this or not (currently looking like not).

I was able to address this in my project with this patch:

I have made a test on Electron Fiddle: https://gist.github.com/NemoAlex/431a61e8464ee6d606f3a02868c66017 Electron 19 Binary uses Node.js 16.14.2, maybe version before 16.14.0(libuv 1.42.0) was fine. Such as Electron 18 uses Node.js 16.13.2, can pass the test. https://github.com/nodejs/node/blob/main/doc/changelogs/CHANGELOG_V16.md

Looks like this was fixed in Electron via https://github.com/electron/electron/issues/35219.
