"Could not determine gpg version"

### Affected version

3.2.6

### Bug description

I am setting up central publishing with maven and have added this maven plugin.
```

org.apache.maven.plugins
maven-gpg-plugin
3.2.6


sign-artifacts
verify

sign

```

upon trying to deploy i receive this error message
"Could not determine gpg version"

I traced this back to [this line of the plugin](https://github.com/apache/maven-gpg-plugin/blob/master/src/main/java/org/apache/maven/plugins/gpg/GpgSigner.java#L74)

After reviewing the regex that is used to get the version `Pattern.compile("gpg \\([^)]+\\) .+");`
And then the regex used to match the value `VERSION_PATTERN = Pattern.compile("(\\d+\\.)+(\\d+)")`

And reviewing my terminal's `gpg --version` call
```
C:\Users\MY_USERNAME>gpg.exe --version
gpg (GnuPG) 2.4.8
libgcrypt 1.11.1

I don't see why this failure has occurred in my build. Any help would be appreciated.

My gpg came from [gpg4win.org](https://gpg4win.org/download.html) as referenced by [gnupg.org](https://www.gnupg.org/download/)

Start in src/main/java/org/apache/maven/plugins/gpg/GpgSigner.java at the version-detection logic and compare its patterns with the reported Windows gpg --version output. Verify how the command output is parsed, then confirm that GnuPG 2.4.8 is detected and signing proceeds without the “Could not determine gpg version” error.
