Browser-sync: Update opn for WSL/Bash on Windows support

[strarsis]

Issue details

opn is required with 4.0.2 by browser-sync (used for opening the browser automatically).
However, this version doesn't work in WSL/Bash on Windows. The latest version works correctly in WSL/Bash on Windows. It would be nice if browser-sync could update opn to its recent release version 5.3.0.

Steps to reproduce/test case

Start browser-sync. Notice this warning:
[Browsersync] Couldn't open browser (if you are using BrowserSync in a headless environment, you might want to set the open option to false)

Please specify which version of Browsersync, node and npm you're running

• Browsersync [2.23.6]

You can use special BS version with updated opn package
Here is the GitHub repo: https://github.com/Kurzdor/browser-sync
And here is the npm package page: https://www.npmjs.com/package/browser-sync-wsl
Tested it on my machine, works greatly.
I will delete this BS version when devs will fix this issue.
Thanks a lot!

@shakyShane: Awesome! Could a new release be
published to npm so I can update browser-sync in the projects?

[shakyShane]

yeah I'll get a release out in the next few hours

Hi, where do I set the browser path? Same issue with browsersync 2.26.7

EDIT: not browsersyncs issue. the WSL distro I was using didn't have /mnt/c in the path, so it wouldn't open a browser. added the path and works fine.
