fix: for unexpected errors in reading versioning config panic (#14994)

Browse Source 
We need to make sure if we cannot read bucket metadata
for some reason, and bucket metadata is not missing and
returning corrupted information we should panic such
handlers to disallow I/O to protect the overall state
on the system.

In-case of such corruption we have a mechanism now
to force recreate the metadata on the bucket, using
`x-minio-force-create` header with `PUT /bucket` API
call.

Additionally fix the versioning config updated state
to be set properly for the site replication healing
to trigger correctly.
