Updating tags causes resource destruction/recreation

[gordon-writer]

Updating the tags of a resource should be possible as an update in-place (for example you can edit the tags in Konnect console).

However when using this provider it forces a destroy/recreate instead of an update in-place. I have observed this for the service and route resources (see output below) when trying to use import blocks to make terraform claim existing Konnect resources.

This has a knock-on effect to any dependent resources: if a service is destroyed and recreated, then it also forces destruction/recreation of resources that reference it in their ID (such as routes).

This makes it more challenging to migrate existing infra seamlessly to be managed by this provider.

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
~ update in-place
-/+ destroy and then create replacement
