Clarify Distribution Management field in POM

### Improvement proposal

According to https://maven.apache.org/pom.html#Repository

> distributionManagement specifies where (and how) this project will get to a remote repository when it is deployed

However @cstamas rather thinks this should be used to indicate where consumers can download it (https://maveniverse.eu/docs/njord/migration/#setup-your-project).

I know that currently even maven-deploy-plugin interprets it like the former, but the question is whether the documentation should be adjusted to indicate its intention.

Read the POM Repository documentation and the linked Njord migration guidance first, then compare the stated meaning with how maven-deploy-plugin interprets distributionManagement. Done means the intended meaning is decided and the relevant documentation wording is updated consistently; the issue does not name a repository file or test.
