…nd transitive dependencies version using kork-bom for upgrading the spring-boot 2.3.x.

While upgrading the spring-boot 2.2.x to 2.3.x, encountered issue of uncontrolled conflict resolution of jackson and kotlin dependencies in gate (spinnaker/gate#1505). In order to avoid any such issue with other components for upgrades to spring-boot 2.3.x as well as for any future spring-boot upgrades, we can introduce strict adherence of imported maven kork-bom by replacing platform to enforcedPlatform closure.
