Adapt to changes in sysinfo

Bumping the `sysinfo` dependency of `gitoxide-core` from 0.31.2 to
0.34.2 broke the a call to `RefreshKind::new()`, because `sysinfo`
0.33.0 renamed `new()` to `nothing()`:
https://github.com/GuillaumeGomez/sysinfo/blob/master/CHANGELOG.md#0330

This renames the call accordingly.
