Remove maximum version constraint for providers

[ryan-jan]

TL;DR

Terraform's best practices specifically state to not constrain the maximum version of providers in shared/reusable modules. It causes such an unnecessary headache - please stop doing this!

Terraform core and provider versions

• Reusable modules should constrain only their minimum allowed versions of Terraform and providers, such as >= 0.12.0. > This helps avoid known incompatibilities, while allowing the user of the module flexibility to upgrade to newer versions of > Terraform without altering the module.

• Root modules should use a ~> constraint to set both a lower and upper bound on versions for each provider they depend on.

Expected behavior

Only constrain the minimum version for any required providers. For example:

    google = {
      source  = "hashicorp/google"
      version = ">= 6.0"
    }
    google-beta = {
      source  = "hashicorp/google-beta"
      version = ">= 6.0"
    }

Observed behavior

Unnecessary dependency hell!

Additional information

I do note that this was raised before, but I think it needs to be revisited as I cannot see any benefit in constraining the maximum versions in these modules - only unnecessary headaches to unpick.
