Implement <Del> as vim insert command ( like <c-h> )

[sql-koala]

Hi VScodeVim Team,
let me start with: Thank you for this extension. I just installed it together with vscode and it feels comfortable (to an experienced vim user).
However, I found one missing feature that seems worth implementing: del> as vim insert command ( in a way that is repeatable and a single undo ).

Is your feature request related to a problem? Please describe.
I think <del> is not implemented in insert mode. I noticed this because I like to map <c-l>to <del>.
When pressing Del key, the vscode command "deleteRight" is probably executed. This does delete the char to the right, but it messes up vim's undo and repeat. Like so: undo does not undo the del, it undoes the last vim command.
This extension provides a command: extension.vim_delete but this is not for insert mode, as it appears.

Describe the solution you'd like
I would suggest to implement this analog to c-h. This is from source insert.js. I think a simple copy + paste and changing position to position + 1 char to the right would to it.

let CommandCtrlHInInsertMode = class CommandCtrlHInInsertMode extends actions_1.BaseCommand {
    constructor() {
        super(...arguments);
        this.modes = [mode_1.ModeName.Insert];
        this.keys = ['<C-h>'];
    }
    exec(position, vimState) {
        return __awaiter(this, void 0, void 0, function* () {
            vimState.recordedState.transformations.push({
                type: 'deleteText',
                position: position,
            });
            return vimState;
        });
    }
};

Describe alternatives you've considered
I mapped <c-l> to <c-o>x and this does the job, but it also "destroys" undo/repeat.
