Formatter destroys slashes in service operation list

[kubukoz]

Tested in 1.57.1.

Input:

$version: "2"

namespace demo

service MyService {
    operations: [
        /// oops
        MyOp
    ]
}

Output:

$version: "2"

namespace demo

service MyService {
    operations: [
        // oops
        MyOp
    ]
}

Additional sample: use ////// hot weather -> gets turned into /// // hot weather, then // // hot weather.

The input and output examples in the issue are what I'd expect, but the other examples look like bugs. I would expect the example you provided because those aren't valid documentation comments, they're just comments. Documentation comments are only relevant if they come before shapes or members, but those in the example come before a shape reference -- there's no member or shape to apply the @documentation trait to, so the formatter notices this, and rewrites the comment to remove ambiguity. (If I had a time machine, I would have made the parser hard fail when we detect this too)
