support by configuring the cache once Spring Data Couchbase has gotten
a chance to be processed.

  Add generated-snippets as output to test goal

Closes gh-22555

See gh-22555

The generated snippets were not declared as an output to the
`spring-boot-actuator-autoconfigure` test goal so when the test was
pulled from the cache, it did not contain the `generated-snippets`
directory. This directory is required as an input to the Asciidoctor
plugin.
