Subject: [PATCH] Unify dotnetup and Microsoft.Dotnet.Installation version

Define DotnetupVersionPrefix and DotnetupPreReleaseVersionLabel in a
shared src/Installer/Directory.Build.props so both projects inherit
the same version. This prevents version drift between the CLI tool
and the library.

Fixes #52795
