Backport #20412 A lot of existing packages do not conform to SemVer, yet, they should be allowed in the Conan package registry as-is. To achieve this, remove the SemVer check from `NewRecipeReference`, and replace it with a simple empty string check. A unit test with a non-semver version is also included. Fixes #20405.
