Service account maximum expiration is not 365 days

[pierresebastien]

Description

The maximum expiration date of service account (introduced in version 3.1.0, see #594) is not 365 days as indicated in the documentation but only approximately 6 days. This is due to a wrong conversion of number of minutes in a year on this line https://github.com/ribetm/terraform-provider-minio/blob/main/minio/resource_minio_service_account.go#L374 (365*24 is the number of hours in a year, not the number of minutes).
