OpenSearch Bug -- Tags updated; but updates are not reflecting in the resource

[thehandsomezebra]

Describe the bug
After creation, we attempt an update of Tags... but tags don't update.

Steps to reproduce

1. Set tags block & let it create (Owner: Steph)
2. change the tag (Owner: Stephanie)
3. Confirm that the tag is updated in the ACK - Domain.. But

Expected outcome
Tag should be (Owner: Stephanie)...

Environment
nonprod & prod.

• Kubernetes version

• Using EKS (yes/no), if so version?
  EKS version 1.32

• AWS service targeted (S3, RDS, etc.)
  OpenSearch ACK Chart - 1.0.0

• Other notes..
  So.. my best guess is that the API is a little different from others with the Opensearch.
  https://docs.aws.amazon.com/opensearch-service/latest/developerguide/managedomains-awsresourcetagging.html

If you add a tag to a domain with the same key as an existing tag, the new value overwrites the old value.

My guess is that the function would need to be to add (which will natively overwrite) rather than some update function.
