Relevant debug or panic output

No response

Expected Behavior

The resource should be created successfully. The provider should either:

• Normalize billing_account_id input (replace - with _) before storing in state, or
• Use a DiffSuppressFunc to treat 03B59F-8AA142-1DBB1A and 03B59F_8AA142_1DBB1A as equivalent

Actual Behavior

│ Error: Provider produced inconsistent result after apply
│
│ When applying changes to datadog_gcp_uc_config.ccm, provider
│ "provider["registry.terraform.io/datadog/datadog"]" produced an
│ unexpected new value: .billing_account_id: was
│ cty.StringVal("03B59F-8AA142-1DBB1A"), but now
│ cty.StringVal("03B59F_8AA142_1DBB1A").
│
│ This is a bug in the provider, which should be reported in the provider's
│ own issue tracker.
