When the `finalName` parameter is incorrectly set in the Spring Boot
Maven plugin configuration instead of in the `build` configuration, the
repackaged and original archive files are not named as expected. Prior
to this commit, the image building goal would detect this error
condition and throw an exception late in the process of creating the
build container, leaving the container in an unstable state. This
commit changes the image building goal to detect this condition early,
before attempting to create the container.
Fixes gh-25590
