deps: Bump github.com/tommy-muehle/go-mnd@v2.2.0 (#1558)

Reference: #1557

Upstream project does not support Go Modules to reference @v2.2.0 directly, so used commit at that tag.

Updated via:

```console
$ go get github.com/tommy-muehle/go-mnd@16041ac3fe65b98fbbf4c3c9b88c346196211614
$ go mod tidy
```
