stardict: Update to 3.0.7

[ryandesign]

Description

Closes: https://trac.macports.org/ticket/69399

It builds for me but I cannot check if it runs because all X11 apps currently crash on my system for an unknown reason.

Since we do not know the maintainer's GitHub handle, GitHub will not notify them of this PR, so I will notify them by email.
