feat: support change calender integration in aws_ssm_association

[lvthillo]

Rollback Plan

If a change needs to be reverted, we will publish an updated version of the library.

Changes to Security Controls

Are there any changes to security controls (access controls, encryption, logging) in this pull request? If so, explain.

Description

Add support for change calender integration in aws_ssm_association. There is no way to create a change calender except using the console so it's hard to test.

Relations

Closes #45318
