This commit skips the Bintray-related tasks in our CI pipeline and
instead relies on Maven Central for publishing Spring Framework
artifacts.
This commit also updates the CI pipeline to sign the artifacts directly
with the `artifactory-resource`.
Closes gh-26654
This commit configures the logging level to DEBUG for the concourse
release scripts tasks.
This is useful to get a clue on where those long-running tasks are at.
This commit adds new tasks to the release pipeline, generating release
notes automatically using the issues in the current milestone and
pushing that as the content of the GitHub release.
Closes gh-25922
