SpringBoot Use activemq-client dependency vs transitional activemq-client-jakarta

Use the activemq-client dependency per: #40027

Ahead of adding embedded broker support in as part of [#38404]

@wilkinsona for your review. This would be cleaner to have in ahead of [#38404].

NOTE: I'll be removing activemq-client-jakarta module in next ActiveMQ 6.x release. (The Maven relocation has been published.)

@wilkinsona re: activemq-bom yep ;-) I've already got a PR for it (https://github.com/apache/activemq/pull/1178) that should land in the next ActiveMQ release.
