Remove no longer needed exclusions from pulsar-client-all

[panic08]

The improvements introduced in this PR include handling javax.activation via shading and migrating from javax to jakarta. Given these changes, we should remove some of the now unnecessary exclusions.

Fix #963

Hi @panic08 - great to see you over here in this project 👋🏻

We just released 1.1.10 and 1.2.4 but will get this merged in soon. We intentionally did not add this change in yet as shadowing, transitive deps, and dependencies in general can be risky beyond the surface, especially when we have something like:

• spring-boot (uses)
  • pulsar-client-all
  • spring-pulsar
  • pulsar-client-reactive
    and
• spring-pulsar (uses)
  • pulsar-client-all
  • pulsar-client-reactive
    and
• pulsar-client-reactive (uses)
  • pulsar-client-all

Thank you very much for the contribution. Once we branch main into 1.2.x and main is then our target for 2.0.0 we will merge this.
