This commit makes sure that a fallback embedded datasource is not
created if no suitable connection pool is found and an url has been
explicitly registered.

This is consistent with EmbeddedDataSourceConfiguration as it is using
EmbeddedDatabaseBuilder behind the scenes and the latter does not
honour the configured URL anyway.

Closes gh-19192

As of spring-projects/spring-framework#22644, Spring Framework caches
the "produces" condition when matching for endpoints in the
`HandlerMapping` infrastructure. This has been improved in
spring-projects/spring-framework#23091 to prevent side-effects in other
implementations.

Prior to this commit, the Spring Boot actuator infrastructure for
`EndpointHandlerMapping` would not clear the cached attribute,
presenting the same issue as Spring Framework's infrastructure. This
means that a custom arrangement with custom `HandlerMapping` or
`ContentTypeResolver` would not work properly and reuse the cached
produced conditions for other, unintented, parts of the handler mapping
process.

This commit clears the cached data and ensures that other handler
mapping implementations are free of that side-effect.

Fixes gh-20150

Closes gh-20106

This commit also upgrades the Spring Boot version used by the scripts
to 2.2.4 which is why the explicit annotation is required.
