fix(testing): Fix format of browser configs (#2444)

Some of the formatting changes made in 

https://github.com/getsentry/sentry-javascript/pull/2437/files#diff-47f8a8c0ffbefeb69466d5cd4ddf7674) 

to the format of `browsers.js` accidentally got overwritten in

https://github.com/getsentry/sentry-javascript/pull/2438/files#diff-47f8a8c0ffbefeb69466d5cd4ddf7674). 

While this doesn't break the BrowserStack tests themselves, it does break the script which checks if our configs are up to date.
