Prefer arguments in POM over spring-boot.run.arguments

This commit changes the order of precedence for the `arguments` property
of the AbstractRunMojo so that values specified in the POM override
values provided on the command line using `spring-boot.run.arguments`.
This brings the `arguments` property in line with all other Mojo
parameters.

Fixes gh-20024
