support `git commit` options within `gitmoji -c`

### Description of the problem

```bash
$ gitmoji -v
8.0.0
```

Currently it is not possible to use `git commit` flags and options when calling `gitmoji -c`.

Because of that some super useful options like `git commit -S` to sign the commits is not possible to be used within that command.

### Solution

add the needed flags as optional parameters to the already supported flags.

### Alternatives

Currently it is possible to add some of the flags to the git global settings. E.g. with the example for `-S`

```bash
git config --global commit.gpgsign true
```

Furthermore (fast reading the code) I think it should be possible to have this functionality using the `--hook` flag.
`gitmoji --hook -S -m ...`. Need to verify.

This is possible but somehow not nice

### Additional context

For me in special the `-S` option is needed and useful. In many projects I want and need to sign commits and should be considered as best practice. For more information please consider https://dev.to/andreasaugustin/git-how-and-why-to-sign-commits-35dn

There are many more useful options which are currently suppressed. Happy to discuss.

Start by tracing how `gitmoji -c` parses its existing options and invokes `git commit`; the issue specifically calls out support for `-S` and other commit flags. Done means commit options can be passed through `gitmoji -c`, with coverage for the requested signing case and any documented supported forms.
