TestAccIntegrationModelAccessResource_updatePricing asserts "0.10" but Terraform normalises to "0.1"

TestAccIntegrationModelAccessResource_updatePricing fails on main.

=== RUN   TestAccIntegrationModelAccessResource_updatePricing
    integration_model_access_resource_test.go:87: Step 2/2 error: Check failed: Check 2/2 error:
    portkey_integration_model_access.test: Attribute 'pricing_config.pay_as_you_go.response_token_price'
    expected "0.10", got "0.1"
--- FAIL: TestAccIntegrationModelAccessResource_updatePricing (13.13s)

Cause: the config at internal/provider/integration_model_access_resource_test.go:291 sets response_token_price = 0.10, and the check at line 123 asserts the string "0.10". Terraform normalises the float to 0.1, so the string comparison fails.

Fix: assert "0.1", or pick a value with no trailing zero.

The same line pair exists for request_token_price = 0.05 / "0.05", which passes because 0.05 has no trailing zero.

Reproduce:

set -a && source .env && set +a
TF_ACC=1 TF_ACC_TERRAFORM_PATH=$(which terraform) \
  go test ./internal/provider -v -run TestAccIntegrationModelAccessResource_updatePricing -timeout 15m
