Missing `ConditionTypeResourceSynced` after updating a CR

[a-hilaly]

(Issue only tested with only s3 for now)

Describe the bug
After updating a CR, it looks like the update code path doesn't append a ConditionTypeResourceSynced to the conditions list.

Steps to reproduce

• Create an s3 bucket resource
• Add a tagging Spec field
• Run k describe bucket <name> / k get bucket <name> -o yaml

Expected outcome
Expecting to see ConditionTypeResourceSynced in Status.Conditions array

Environment

• Using EKS (yes/no), if so version? 1.20.4
• AWS service targeted: s3
