bug#63141: Incorrect indentation in csharp-mode

Yes, it is.

csharp-mode has the following:

```elisp

(c-add-style "csharp"
             '("java"
               (c-basic-offset . 4)
               (c-comment-only-line-offset . (0 . 0))
               (c-offsets-alist . ((inline-open           . 0)
                                   (arglist-intro         . +)
                                   (arglist-close         . 0)
                                   (inexpr-class          . 0)
                                   (case-label            . +)
                                   (cpp-macro             . c-lineup-dont-change)
                                   (substatement-open     . 0)))))

```

I consider it an awkward indentation, so better to change the default (change to the expected behavior).

Isn't this user preference that is customizable via c-offset-alist?
