Private CA Certificates in wrong format (extra tab)

I have a PrivateCA which has a "RootCA" that is in my control and the "Intermediary CA" that is run on the AWS hardware (a pretty standard setup).

When running this command the output is (as expected) a certificate chain file-

```
aws acm-pca get-certificate
--certificate-authority-arn ""
--certificate-arn ""
--output text > example.crt
```

The actual certificates themselves are fine, however there's an extra "tab" between the end of the first certificate and the start of the second one.

```
-----BEGIN CERTIFICATE-----
MIIFqDCCA5KgAwIBAgIRAL+jWvEn+XbyVX0EOUEISrYwCwYJKoZIhvcNAQELMHkx

-----END CERTIFICATE-----
```

This tab is consistently there with all of the certificates I sign and retrieve, and it breaks the certificate chain formatting. While this bug persists it's impossible to get a working chain file directly from the AWS CLI- instead the output has to be filtered to remove the random tab or applications like nginx will choke on the certificate chain.
