[Enhancement]: aws_amplify_domain_association certificate_settings AMPLIFY_MANAGED should be default

[rsi-mrobinson]

Description

the newly added (>=5.57.0) certificate_settings attribute should default to AMPLIFY_MANAGED rather than null. Existing resources appear to result in plans where the certificate settings are being removed, despite amplify managed domains being the default up to this point. The new certificate setting block should respect this an only be required to override the default settings.

Hey @rsi-mrobinson 👋 Thank you for taking the time to raise this! To make sure I understand -- you're saying that if you update the version and make no other configuration changes, resources are being replaced on the next apply?

[rsi-mrobinson]

That's correct, if you upgrade to 5.57 or above without making changes to this resource, the plan shows a change to remove the default amplify managed dns

Hey @justinretzolk @rsi-mrobinson I can take this issue up, just to be clear the only change would be to add Default : "AMPLIFY_MANAGED" here right?
