Document deprecations in PrepareReleaseMojo and PerformReleaseMojo (#1448)

Improved documentation for deprecated parameters:
- generateReleasePoms: explained deprecation and pointed users to
  release:prepare-with-pom.
- useReleaseProfile: clarified that the super POM release-profile is
  being removed and projects should rely on explicit profiles instead.

No functional changes. Build verified.
