ci(release): clone ldid from ProcursusTeam GitHub mirror (#11990)

The upstream `https://gitlab.com/opensource-saurik/ldid.git` is no
longer publicly accessible (returns 401 / redirects to sign-in), so
`git clone` prompts for a username and fails non-interactively with
`could not read Username for 'https://gitlab.com'`. This blocks every
v10 release.

`ProcursusTeam/ldid` is a maintained GitHub fork that contains the
exact commit the workflow pins (c2f8abf), and the libplist submodule
already points at github.com, so a one-line URL swap is the full fix.
