Add Imgur Redirection Support about browser_extension

[ManeraKai]

Till now we've added Rimgo.

We have decided not to add Imgin and Rimgu. Because, There seems to be no Public Instance of Rimgu. And Rimgo - A fork based on Rimgu is good and seems to be well maintained with a Decent list of Instances.

In the case of Imgin there is only one Instance - https://imgin.voidnet.tech/. It lacks features such as playing GIFs, Videos and has Stats such as No of views, Likes. Date/Time of Post. Support of User Profiles, Tags, Comments, etc. Which Rimgo does provide.

So, Adding the other two would be waste of resources for us. I hope you understand the point here.

Though if they got more support and features. We'll add them.
