Modify access key secret and bucket name in docs

AWS secret code needs to be corrected
Here is the documentation link:
https://docs.redhat.com/en/documentation/red_hat_openshift_logging/6.3/html/installing_logging/installing-logging#install-loki-operator-cli_installing-logging:~:text=Create%20a%20secret%20with%20the%20credentials%20to%20access%20the%20object%20storage.%20For%20example%2C%20create%20a%20secret%20to%20access%20Amazon%20Web%20Services%20(AWS)%20s3.
Here is the current look:
9. Create a secret with the credentials to access the object storage. For example, create a secret to access Amazon Web Services (AWS) s3.

apiVersion: v1
kind: Secret
metadata:
  name: logging-loki-s3  1
  namespace: openshift-logging
stringData:  2
  access_key_id: <access_key_id>
  access_key_secret: <access_secret>
  bucketnames: s3-bucket-name
  endpoint: https://s3.eu-central-1.amazonaws.com
  region: eu-central-1
`access_key_secret` value is wrongly mentioned.
It needs to be corrected. The correct value is `access_key_secret`
Here is the updated look:
9. Create a secret with the credentials to access the object storage. For example, create a secret to access Amazon Web Services (AWS) s3.

apiVersion: v1
