[lib] Bump detect-browser version
Summary:
We're using an old version that has more limited browsers support. According to the release notes https://github.com/DamonOehlman/detect-browser/releases/tag/v5.0.0 the major version was increased because of a breaking change that removed support for one browser.
Test Plan: Tested on iOS that the correct version is detected in the responder.
