[GUI Functional] Reduced number of supported browser versions

From functional testing perspective, it doesn’t make sense to use old browser versions to run GUI Funcitonal tests. So we reduced the number of available in Blazemeter versions to last 6.

You’ll also start receiving warnings in tests and reports in case you have a browser in a test older than last 3 versions.

Please, find more info in the guides article.
