[Bug] problems in developer/general/setup-configuration-web.html page

[kkoynov]

Description

• Again we depend on .net v4.6.2

• There is a closing emphasis tag

• We should remove the part at the end about IE11 support as currently the web sdk doesn't work on IE11 as it is the case with the app.

• "There is a closing emphasis tag" - where? Not sure I see what you mean by this.

• Removed the whole "IE11 Support" section.
