Add a CI action to verify the windows build works on Windows 10 1809

[paperclover]

the minimum version bun windows supports is this version.

it would be nice if we had a CI check that verifies the build properly works:

this user spent extra time getting around "failed to verify bun.exe" because the install script refused to install bun. once the issue is identified it took two lines to fix (see #8477)

this should not be something a user does but rather something we get in our own CI.

imo it should run on PRs, where a windows 10 1809 machine does bun --version. if there are newer apis used then the binary will not open.

another option is to run the whole test suite on such machines. this might be harder and may be something we want to do less frequently.
