This auto-configuration ensures, if Micrometer Tracing is on the
classpath, that there is always a tracer. It backs off if there is
already a tracer, for example contributed by the Brave or the Otel
auto-configurations, which are run before.

Prior to this commit, we set in gh-37388 the ObservationRegistry on the
auto-configured JmsTemplate bean. This enables observations and context
propagation when sending JMS messages.
This commit applies the same to the `DefaultJmsListenerContainerFactory`
and the `DefaultJmsListenerContainerFactoryConfigurer`, in order to
enable observations on `@JmsListener` annotated methods.
This commit also refactors the support implemented in gh-37388 to avoid
relying on a bean post processor and instead set the observation
registry directly in the main auto-configuration: while Micrometer core
is an actuator-only dependency, Micrometer Observation API is a compile
dependnecy for spring-jms itself and there is no need to separate
concerns there.

Previously, the child management context was created when the
parent context's web server was initialized and it wasn't stopped
or closed until the parent context was closed. This resulted in
the child context being left running when the parent context was
stopped. This would then cause a failure when the parent context
was started again as another web server initialized event would be
received and a second child management context would be started.
This commit updates the initialization of the child management
context to integrate it with the lifecycle of the parent context.
The management context is now created the first time the parent
context is started. It is stopped when the parent context is
stopped and restarted if the parent context is started again.
This lifecycle management is done using a phase that ensures
that the child context is not started until the parent context's
web server has been started.

The mocks being static meant that their state was shared across each
test in the class. This resulted in the tests being order dependent.
This commit uses instance variables to hold the mocks, thereby
ensuring that they're recreated for each test as part of the standard
JUnit lifecycle.
Closes gh-38363
This introduces two different attributes for, e.g. the Spring Framework
version: the "normal" one, e.g. 6.1.0-SNAPSHOT, and the Antora one,
e.g. 6.1.
Spring Framework's reference documentation is still broken when using
SNAPSHOT versions, see spring-framework/gh-31480.
