Bug: Incorrect XML tag in VersioningConfiguration model

[benjamin3322]

Issue description:

The Minio client serializes the VersioningConfiguration model and sends it as XML to an S3 compliant server. However, it defines the XML tag for MfaDelete incorrectly as <MFADelete>, whereas according to the XSD (XML Schema Definition) for S3, it should be <MfaDelete>. This inconsistency in tag naming breaks XML validation when interacting with S3 compliant servers.

Actual Behavior:

The Minio client serializes the VersioningConfiguration model with the incorrect XML tag <MFADelete>, causing XML validation errors when interacting with S3 compliant servers.
