Unwanted dependency on liquibase-commercial

[meisenla]

Since version 4.27.0 liquibase-oracle has a dependency on liquibase-commercial due to changes in liquibase-parent-pom. This forces the dependency on projects that do not use Liquibase Pro. This was found in a project that uses Liquibase on H2 and Oracle databases. If liquibase-oracle and liquibase-commercial are in the classpath together, the execution on a H2 database fails.

I have also created issue liquibase/liquibase-parent-pom#168 on liquibase-parent-pom.
