♻️ Improved code editor detection (#60)

Now correctly detects the following apps that can open a directory:

- PhpStorm (installed via Toolbox)
- Sublime Text
- Sublime Merge

This in addition to:

- PhpStorm (manual installation)
- Visual Studio Code

These need to be installed in the default location.
For VS Code to work, you need to have added `code` to your PATH.

+
+When you select and right-click on a domain, you can open these directories with various applications. This can help speed up your workflow. However, for these apps to show up, they must be detected first.
+
+The supported apps are: <i>PhpStorm, Visual Studio Code, Sublime Text, Sublime Merge</i>.
+
+For <strong>Visual Studio Code</strong>, you need to have `code` available in your PATH. [More info](https://code.visualstudio.com/docs/editor/command-line) here.
+
+For <strong>Sublime Text (and Sublime Merge)</strong>, the apps need to be in your `/Applications` directory.
+
+For <strong>PhpStorm</strong>, both a standalone installation (in `/Applications`) and an installation via JetBrains Toolbox are can be detected. If you happen to have both installed, they are listed separately.
+
+To see which files are checked to determine availability, see [this file](./phpmon/Domain/Helpers/Editor.swift).
