Maven central rules: Inherited <url> or <description> from parent pom should not fail the build

[ge0ffrey]

When validating an artifact with a pom that lacks an <url> or <description> element, but inherits it from its parent pom, the maven central rules should not fail.

Currently, even though it says "Will use computed value from parent:", it fails the build in pomchecker in JReleaser:

Proposal A): report these as warnings, not errors.

Proposal B): do not report these at all, it's fine. For example, repeating the <url> in every child pom of a maven multiproject would violate DRY.

Pomchecker offers 2 flags --fail-on-error and --fail-on-warning that can also be invoked in negated form https://kordamp.org/pomchecker/pomchecker-cli/index.html

The default setting is to fail on error and warning https://github.com/kordamp/pomchecker/blob/2577609ef49adb0873932393a50e80f6afe0d5b1/pomchecker-cli/src/main/java/org/kordamp/maven/checker/cli/CheckMavenCentral.java#L45
