fix: allow setting offpeakwindow at 00:00

[taktakpeops]

Description

Address the issue #32701 by allowing the user to set an offpeakwindow for an aws_opensearch_domain resource at 00:00 (it's the default behaviour when enabling it using the AWS CLI (https://docs.aws.amazon.com/opensearch-service/latest/developerguide/off-peak.html#off-peak-enable -> If you don't specify a custom window start time, it defaults to 00:00 UTC.).
