Add --browser cli argument for changing the default browser

[zdravko-georgiev]

Is your feature request related to a problem? Please describe.

Using ui5 serve --open will open the server root directory in the default browser. But if you want to use a browser different than the default system browser, there is no way to specify it.

Describe the solution you'd like

The open package used by the ui5-tooling supports this feature. A simple solution could be adding an additional cli argument, e.g. --browser when one can specify the browser to be used, e.g. chrome|firefox|edge, the value can be then used when executing the open request.

Describe alternatives you've considered

Copying link and manually opening it in the desired browser

Sounds like a good suggestion. The API is documented here: https://github.com/sindresorhus/open#usage

Maybe we should look into this together with: #623
