Incorrect formatting of hover action

[BenjaminBrienen]

rust-analyzer version: rust-analyzer version: 0.0.0 (75b2232 2022-07-03)
rustc version: rustc 1.64.0-nightly (1517f5de0 2022-07-07)

relevant settings: rust-analyzer.hover.actions.references.enable

You can see there is a triple underscore ___ between references and ▶︎. This is caused by the .join() here:

Is the ___ there for a particular reason, @vsrs ?

I don't have write access but I would propose the following change to that function:

function renderHoverActions(actions: ra.CommandLinkGroup[]): vscode.MarkdownString {
    const text = actions
        .map(
            (group) =>
                (group.title ? group.title + " " : "") +
                group.commands.map(renderCommand).join(" | ")
        )
        .join("  /  ");

    const result = new vscode.MarkdownString(text);
    result.isTrusted = true;
    return result;
}

We might want to make the hover popup have the same format as the CodeLens: Run | Debug | N references

Requires

    "rust-analyzer.lens.references.method.enable": true,
    "rust-analyzer.hover.actions.references.enable": true,

to be able to see this behavior.
