Prior to this change, Signal-Desktop was using a rather ancient version of `mkdirp`, which was meant for Node.js versions without native support for this kind of functionality. Starting with Node v10, `fs.mkdir()` can perform recursive directory creation. Since Signal-Desktop doesn't utilize any advantages of using such an old version of `mkdirp` [1] (let alone any version of `mkdirp`), we can replace it with the native methods of `fs` (or `fs/promises`). This transition slightly reduces the amount of packages needed to be downloaded and included in the final app since it now relies on the built-in API of Node.js.
