Cache module does not allow to suppress uppercase "Environment" tag for S3 bucket resource

[roberts-b]

Describe the Bug

In our organization AWS accounts we strict rules about environment tag name that it should be lowercase.

Issue

There is functionality to suppress default AWS tags using
suppressed_tags = ["Environment"]
Which is working fine for most of resources created by this module, only cache S3 bucket creation is attempted with the uppercase Environment tag name and it fails for us.

Expected

suppressed_tags = ["Environment"]
statement also suppresses uppercase Environment tag creation also for cache S3 bucket.
