Rework `AbstractApplicationContextRunner.withBean` methods to
align signatures as much as possible with those provided by
the `ApplicationContext`.

Also update the implementation to use a dedicate member
variable rather than adding initializers.

Since the transport client has been deprecated in gh-15008, the health
indicator for that should be deprecated as well.

This commit introduced an incompatible change in the asciidoct
API: both asciidoctorj-pdf and spring-asciidoctor-extensions
expect `org.asciidoctor.extension.JavaExtensionRegistry` to be
a class, not an interface.

This reverts commit 120ffb1e.

The move to an HTTPS URL for the xmlns:xslt identifier has the unwanted
side-effect of disabling indentation.

This commit moves back to an HTTPS URL. It also changes the indent size
to 2, aligning with the size used by all the other poms that are written
by the flatten plugin.

As of Spring Data Moore, the Elasticsearch high level REST client is
supported for Spring Data repositories. The transport client is now
deprecated and is likely to be removed in a future Spring Data release.

This commit deprecates the transport client and marks all the associated
configuration properties as deprecated. The Spring Boot starter depends
on the `spring-data-elasticsearch` project, which now depends on both
transport client and high level REST client.

This commit also deprecates the Jest client, as Spring Boot will focus
on supporting the high level REST client and the reactive client
provided by Spring Data - both being in sync with the fast release pace
of Elasticsearch.
