Diagnostics.AddAttributeWarning does not redact value for attribute marked as sensitive

The warning message for an attribute that has been marked as "Sensitive" shows the value in the console.

I suspect similar misbehavior for error message?

### Module version

```
github.com/hashicorp/terraform-plugin-framework v1.8.0
```

### Relevant provider source code

```go
resp.Diagnostics.AddAttributeWarning(
req.Path,
"Usage of GPG can't be validated.",
"Due to limitations of go libraries, your GPG key can't be validated client side.",
)
```

### Terraform Configuration Files

N/A

### Debug Output

```console
│ Warning: Usage of GPG can't be validated.
│
│ with artifactory_keypair.some-keypair-6543461672124900137,
│ on cdk.tf.json line 2802, in resource.artifactory_keypair.some-keypair-6543461672124900137:
│ 2802: "private_key": "-----BEGIN PGP PRIVATE KEY BLOCK----- -----END PGP PRIVATE KEY BLOCK-----",
│
│ Due to limitations of go libraries, your GPG key can't be validated client
│ side.
```

### Expected Behavior

The value of the sensitive attribute should either be redacted or hidden completely.

### Actual Behavior

The value is output verbatim to the console.

### Steps to Reproduce
