fix: build arm64 binaries

[julian-dolce-form3]

Build arm64 binaries. This is required for Apple Silicon.

Initial build was failing with the following errors.

Step 1/2 error: unsupported state format version: expected ["0.1" "0.2"], got "1.0"

The resolution for this was described here, which required an upgrade of github.com/hashicorp/terraform-plugin-sdk/v2. Updating to the latest version of that also bumped the Go Version to 1.17.

Testing done:

• Unit tests all pass
• bundle tested locally with terraform init on Apple Silicon
• We can't test this on a real plan without jumping through a lot of hoops so we tested it locally in a test module

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # module.auth0_mod[0].auth0_user.test_user will be created
  + resource "auth0_user" "test_user" {
      + connection_type = "Username-Password-Authentication"
      + email           = "[email protected]"
      + email_verified  = true
      + id              = (known after apply)
      + name            = "test-user-api.api.test.com"
      + password        = (sensitive value)
      + user_id         = (known after apply)
      + user_metadata   = (known after apply)
    }

  # module.auth0_mod[0].random_uuid.test_user_password will be created
  + resource "random_uuid" "test_user_password" {
      + id     = (known after apply)
      + result = (known after apply)
    }

Plan: 2 to add, 0 to change, 0 to destroy.

────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if you run "terraform apply" now.

LGTM - thanks for the detailed testing description.
