package/git: security bump to version 2.31.7
Fixes the following security issues:
* CVE-2023-22490:
Using a specially-crafted repository, Git can be tricked into using
its local clone optimization even when using a non-local transport.
Though Git will abort local clones whose source $GIT_DIR/objects
directory contains symbolic links (c.f., CVE-2022-39253), the objects
directory itself may still be a symbolic link.
These two may be combined to include arbitrary files based on known
paths on the victim's filesystem within the malicious repository's
working copy, allowing for data exfiltration in a similar manner as
CVE-2022-39253.
* CVE-2023-23946:
By feeding a crafted input to "git apply", a path outside the
working tree can be overwritten as the user who is running "git
apply".
