Add alternate names for Profile Directory

[makisukurisu]

Windows version of Zen uses the Profile Folder name instead of Profile Directory in about:support, example:

Linux:

Windows:

A friend of mine was trying to find the exact match to Profile Directory, and couldn't find it.

Just a suggestion - perhaps Windows version of the app just shouldn't rename the properties here for no apparent reason.
While Folder and not Directory is a bit clearer for Windows users, I don't think that it matters all that much.

But I suppose that's a suggestion for https://github.com/zen-browser/desktop repo, and not the docs.

Another idea would be to add the aliases (like a subscript) in Windows builds, but I digress.
