feat(systeminfo): include Git hash and branch in system information log (#4167)

I suggest to add the commit hash and branch to the system information.
This should help trouble shooting issues from developers. Like in #4165.

### before

```
####  System Information  ####
- SYSTEM:   manufacturer: Micro-Star International Co., Ltd.; model: MS-7D75; virtual: false; MM: v2.37.0-develop
- OS:       ...
...
```

### after

```
####  System Information  ####
- MM:       version: v2.37.0-develop; git: 03e4eef; branch: develop
- SYSTEM:   manufacturer: Micro-Star International Co., Ltd.; model: MS-7D75; virtual: false
- OS:       ...
...
```
