Update gem release action

[sarcilav]

This update includes a gix on the action to handle git safe.directory config

git-config: safe.directory

These config entries specify Git-tracked directories that are considered safe even if they are owned by someone other than the current user. By default, Git will refuse to even parse a Git config of a repository owned by someone else, let alone run its hooks, and this config setting allows users to specify exceptions, e.g. for intentionally shared repositories (see the --shared option in git-init[1]).

This is a multi-valued setting, i.e. you can add more than one directory via git config --add. To reset the list of safe directories (e.g. to override any such directories specified in the system config), add a safe.directory entry with an empty value.

This config setting is only respected when specified in a system or global config, not when it is specified in a repository config or via the command line option -c safe.directory=<path>.

The value of this setting is interpolated, i.e. ~/<path> expands to a path relative to the home directory and %(prefix)/<path> expands to a path relative to Git’s (runtime) prefix.
