Allow inplace update of description for stackit_secretsmanager_user

[slm0n87]

Problem description

I want to update the description for the secrets-manager user but terraform wants to replace whole resource (leads into new username + password) instand of only updating this attribute.

Proposed solution

The resource should be updated in-place.

-/+ destroy and then create replacement

Terraform will perform the following actions:

  # module.stackit.stackit_secretsmanager_user.dns["dns-api-prd"] must be replaced
-/+ resource "stackit_secretsmanager_user" "dns" {
      ~ description   = "User for dns-api-prd" -> "The description for my user" # forces replacement
      ~ id            = "xxxxxxxxxxx,xxxxxxxxxx" -> (known after apply)
      ~ password      = (sensitive value)
      ~ user_id       = "xxxxxxxxxxx" -> (known after apply)
      ~ username      = "smxxxxxxxxxxxxx" -> (known after apply)
        # (3 unchanged attributes hidden)
    }

Plan: 1 to add, 0 to change, 1 to destroy.

Alternative solutions (optional)
