`UnicodeDecodeError` if commit messages contain Unicode characters
### Description

If I run
```
cz changelog
```
and the commit messages contain Unicode characters like 🤦🏻‍♂️ (which is an eight-byte utf-8 sequence: `\xf0\x9f\xa4\xa6 \xf0\x9f\x8f\xbb`) then I get the following traceback
```
Traceback (most recent call last):

UnicodeDecodeError: 'charmap' codec can't decode byte 0x8f in position 1689: character maps to <undefined>
```
The result of `chardet.detect()` here

https://github.com/commitizen-tools/commitizen/blob/2ff9f155435b487057ce5bd8e32e1ab02fd57c94/commitizen/cmd.py#L26

is:
```
{'encoding': 'Windows-1254', 'confidence': 0.6864215607255395, 'language': 'Turkish'}
```
An interesting character encoding prediction with a low confidence, which in turn picks the incorrect codec and then decoding the `bytes` fails. Using `decode("utf-8")` works fine. It looks like issue https://github.com/chardet/chardet/issues/148 is related to this.

I think the fix would be something like this to replace [these lines of code](https://github.com/commitizen-tools/commitizen/blob/2ff9f155435b487057ce5bd8e32e1ab02fd57c94/commitizen/cmd.py#L23-L31):
```python
stdout, stderr = process.communicate()
return_code = process.returncode
try:
    stdout_s = stdout.decode("utf-8")  # Try this one first.
except UnicodeDecodeError:
    result = chardet.detect(stdout)  # Final result of the UniversalDetector’s prediction.
    # Consider checking confidence value of the result?
    stdout_s = stdout.decode(result["encoding"])
try:
    stderr_s = stderr.decode("utf-8")  # Try this one first.
except UnicodeDecodeError:
    result = chardet.detect(stderr)  # Final result of the UniversalDetector’s prediction.
    # Consider checking confidence value of the result?
    stderr_s = stderr.decode(result["encoding"])
return Command(stdout_s, stderr_s, stdout, stderr, return_code)
```

### Steps to reproduce

Well I suppose you can add a few commits to a local branch an go crazy with much text and funky unicode characters (emojis with skin tones, flags, etc.), and then attempt to create a changelog.

### Current behavior

`cz` throws an exception.

### Desired behavior

`cz` creates a changelog.

### Screenshots

_No response_
