fix(analytics-browser): prevent error being thrown when server-side rendering

[johnf]

Summary

Fixes #710 - I'm not sure why, but this library gets pulled into the SSR part of my next.js project. Likely a treeshaking issue. It then throws and error because navigtator is missing.

@izaaz Any chance of getting this merged?

[johnf]

@izaaz I've added some extra places where SSR causes issues

[izaaz]

@johnf - created a new PR for this https://github.com/amplitude/Amplitude-TypeScript/pull/876

For the other two plugin changes, we've already made changes to use getGlobalScope()?.addEventListener instead of window.addEventListener which should have fixed those problems already. Can you please take a look at the other PR and approve it if it looks good?

Closing in favour of #876

[izaaz]

@johnf this should be now available in version 2.11.7. Please let me know if you run into issues
