[MWRAPPER-107] Windows script fails to process userinfo

The build fail when the [userinfo field](https://maven.apache.org/wrapper/index.html#using-basic-authentication-for-distribution-download) is set in the distributionUrl for type only-script, but only for mvnw.cmd. The mvnw scripts runs without error on Linux.

```
C:\git\tester [tester ≡]> .\mvnw.cmd clean -N

**Affects:** 3.2.0

Start with mvnw.cmd and compare its handling of distributionUrl userinfo with the Linux mvnw script. Reproduce the issue with .\mvnw.cmd clean -N using the documented basic-authentication setup; done means the Windows wrapper downloads the distribution without the 401 error and starts Maven.
