Production build should not reference sourcemap

[lonix1]

The production build aspnet-validation.min.js references a source map due to this trailing comment:

//# sourceMappingURL=aspnet-validation.min.js.map

That unfortunately spams the devtools console on every page load. Example from my dev machine:

Source map error: request failed with status 404
Resource URL: http://localhost:5000/aspnet-validation.min.js?v=Uz3ITHpf7A137fljWz3TgkiLOAuuH8-EUPTNuZ_GrLw
Source Map URL: aspnet-validation.min.js.map

The production build should not have source map support, because it's unnecessary, it spams the console and generates significantly more traffic (lib is ~21KiB and map is ~83KiB).

(This is probably affecting your users too.)
