Windows installer does not register stack version

[lunacd]

General summary/comments (optional)

With Windows Package Installer (winget), a package needs to register its version with Windows. Otherwise winget constantly thinks that there is an upgrade.

I realize that this is not a stack issue specifically and that you guys owe us users nothing (we owe you guys for the work and awesome product). If somebody can give me a pointer to how the windows installer is currently packaged (I can't find it...), I can go fix it through a PR.

Steps to reproduce

Install stack. Go to Control panel -> Programs and Features. Look for Haskell Stack.

Expected

Windows should recognize Stack's version.

Actual

No version is registered.

Stack version

$ stack --version
Version 2.7.3, Git revision 7927a3aec32e2b2e5e4fb5be76d0d50eddcc197f x86_64 hpack-0.34.4

Method of installation

• Official binary, downloaded from stackage.org or fpcomplete's package repository

I think the key DisplayVersion needs to be added to this script: https://github.com/commercialhaskell/stack/blob/master/etc/scripts/build-stack-installer.hs.

See microsoft/winget-cli#1255 (comment) for more information. Unfortunately, I'm not sure how to retrieve the version number. I think it needs to be passed as an argument to the build-stack-installer.hs script from https://github.com/commercialhaskell/stack/blob/master/etc/scripts/release.hs. But I couldn't figure out more, just yet.

Edit: I guess there is the function stackVersionStr in the release.hs.

Added PR #5660 adding DisplayVersion, which enables winget to properly read the installed version.
