Can't release both Mac and Windows zip files

When publishing a release that contains zip files for more than one platform, only one of them will be published. The first set to be released wins: so if I release the Windows version first, then when I come to release the Mac version there is already a release zip file and no Mac zip file will be released. This means upgrades now fail on Mac.

The issue seems to be that this method in `BaseDriver.ts`:

```
/**
* This method compares to file names to determine if they are technically the same
* file in the context of a single version/platform/arch combination. This is used
* to ensure we never upload two -full.nupkg files to a single version, or two .dmg
* files.
*
* @param file1 The name of the first file
* @param file2 The name of the second file
*/
protected isInherentlySameFile(file1: string, file2: string) {
for (const suffix of IDENTIFYING_SUFFIXES) {
if (file1.endsWith(suffix) && file2.endsWith(suffix)) {
return true;
}
}
return false;
}
```

This falsely concludes that just because both are zip files, they are 'inherently the same file' leading the first one to win and the second one to be discarded. It should check additional parts of the filename to match platform strings.

Workaround: Always release the Mac files first.

Start in BaseDriver.ts at isInherentlySameFile and inspect how IDENTIFYING_SUFFIXES and platform parts of filenames are used. Confirm that zip files for different platforms can both be released, while duplicate files for the same platform and version are still rejected.
