Added button to copy file name in PR files

[saneks222]

The merge request file viewer has a button for copying the file path, but it is not always convenient. Often, you only want to copy the file name, which is currently not possible. This change request adds this capability.

It seems to be a duplicate button.

Thank you for your reply!
If you think this button is redundant here, perhaps we could move it here? What do you think about this option?

Call it "Copy filename" and have it in that menu, yes.

I moved the button to the menu and also attempted to add localization, but encountered issues with Chinese dialects, so I was unable to add localization for it

No need to make other translations. The only thing need to do is to add the en-US. Other languages will be handled by Crowdin.

By the way, there could be some improvments:

1. No need to introduce ShortName. You can call data-xxx="{{$file.GetDiffFileShortName}}" directly from template
2. It should use path.Base but not filepath.Base

Thanks for the review!
Fixed.
