Change endpoint format for per-bucket metrics (#19655)

Per-bucket metrics endpoints always start with /bucket and the bucket
name is appended to the path. e.g. if the collector path is /bucket/api,
the endpoint for the bucket "mybucket" would be
/minio/metrics/v3/bucket/api/mybucket

Change the existing bucket api endpoint accordingly from /api/bucket to
/bucket/api
