K8SPSMDB-1520: implement native Minio support

[mayankshah1607]

CHANGE DESCRIPTION

This PR adds a new backup storage type minio. This storage type has been added to PBM 2.12.0. Since not all S3-compatible storage services support AWS SDK v2's Signature Version 4 (SigV4), the minio storage type uses the Minio client instead of the AWS SDK.

Example:

backup:
  image: perconalab/percona-server-mongodb-operator:main-backup
  storages:
     minio:
       type: minio
       minio:
         bucket: MINIO-BACKUP-BUCKET-NAME-HERE
         region: us-east-1
         credentialsSecret: my-cluster-name-backup-minio
         endpointUrl: minio.psmdb.svc.cluster.local:9000/minio/
         insecureSkipTLSVerify: false
         prefix: ""
         secure: false

Pull Request Overview

This PR implements native Minio support for MongoDB backups as an alternative to S3-compatible storage. The implementation adds Minio as a separate BackupStorageType because not all S3-compatible storage services support AWS SDK v2's Signature Version 4 (SigV4). The change uses the MinIO Go client from PBM (v2.12.0+) instead of the AWS SDK.

Key Changes:

• Added BackupStorageMinio type with dedicated configuration struct (BackupStorageMinioSpec and MinioRetryer)
• Refactored GCS endpoint URL constant to a shared pkg/naming package for better code organization
• Updated PBM library dependency to version with Minio storage support
• Extended backup and restore controllers to handle Minio storage type

• The default backup image has changed from a stable version (percona/percona-backup-mongodb:2.11.0) to a development image (perconalab/...main-backup). This could cause instability in tests and production environments. Consider using a stable version tag instead of 'main' which points to potentially unstable code.

[nitpick] The storage name 'minio-s3' is misleading since this configuration still uses S3 type. Consider renaming to 'minio-via-s3' or 'minio-s3-compatible' to clarify that this is the S3-compatible approach, distinct from the new native 'minio' type.
