[bitnami/kafka] IpFamilies and IpFamilyPolicy configurables

[Yhasmina]

Description of the change

Add the ability to configure the ipFamilyPolicy and ipFamilies in services. This is something that is needed in some environments where exists dual stack but we want to prefer just ipv6 ips, for example.

Benefits

It's possible to modify the ipFamilies and ipFamilyPolicy of all of the services of kafka deployment.

Additional information

By default the values are:

global:
  ipFamily:
  - IPv4
  ipFamilyPolicy: SingleStack

Thanks, @bitnami-bot was able to update the branch, see 8dfa101.

It seems there are some conflicts that you need to solve before going ahead. Could you please rebase from main and solve the conflicts?

[Yhasmina]

@carrodher Conflicts solved. thanks

[carrodher]

Unfortunately there are still some conflicts, see

Sorry @carrodher , i don't understand why now is failing the [CI/CD] CI Pipeline / Get modified charts (pull_request_target) step, because i dind't change anything related to that in these days. I've added the new version of the chart in Chart.yaml file and also in the changelog.md. What else is needed?

Thanks

The error is

Error: Detected changes in charts without version bump in Chart.yaml. Charts changed: 1. Version bumps detected: 0

If there was a new release (#31624) and you rebased the changes from main, you will need to bump the chart version again, otherwise, it will use the one already in main.

Taking a look at the modified files (https://github.com/bitnami/charts/pull/31456/files), there are no changes in the Chart.yaml
