Allow package name to contain hyphens, even on win32

[benjamin-heasly]

Could get-package-info output the package name as-is on all platforms, instead of replacing the hyphens - with underscores _ on win32?

This question is motivated by recent honeycomb work with electron-forge v6. I found that the electron-forge Windows package maker @electron-forge/maker-squirrel is outputting installer names like
hello-honeycomb-2.3.1 Setup.exe
Where the file name preserves the hyphen in the package name, hello-honeycomb.

Using get-package-info I could almost construct this name as

${{ steps.package_info.outputs.package_name }}-${{ steps.package_info.outputs.package_version }} Setup.exe

But since the package_name had its hyphen converted to an underscore, the closest I could get was
hello_honeycomb-2.3.1 Setup.exe

I think this is a (new?) use case where we'd want to keep the hypen, even on win32.

Instead of having platform-specific behavior, could get-package-info provide both versions of the name outputs? Perhaps:

• package_name -- the name from package.json as-is
• package_name_with_underscores -- the name with hypens replaced with underscores

Then from any platform, win32 or other, users could consume the value they need.
