Add support for ap-south-2 by bumping minio-go

[aittam]

Thanos, Prometheus and Golang version used:

thanos v0.31.0
prometheus v2.43.0

Object Storage Provider:
s3

What happened:

thanos-store-0 is crashlooping when running in AWS ap-south-2

What you expected to happen:

to work exactly as in any other region

How to reproduce it (as minimally and precisely as possible):

On the AWS portal, activate the region ap-south-2, the deploy Thanos on EKS with a conf like:

type: S3
config:
  bucket: myBucket1dh73j83jd8jd
  region: ap-south-2
  endpoint: s3.ap-south-2.amazonaws.com
  sts_endpoint: sts.ap-south-2.amazonaws.com

Anything else we need to know:
I see minio-go introduced the support for that region in version v7.0.61, see minio/minio-go@5d09d8f
