Makefile should not auto-compute Pulumi CLI version from go.mod file

[rquitales]

While on-boarding awsx and aws-apigateway, it was observed that the installed Pulumi CLI version is auto-computed from the provider's go.mod file. This is fine for Go based providers, but we now manage NodeJS based providers like awsx and aws-apigateway. We need better handling of Pulumi CLI versions as the one defined in the go.mod file may not be the same as the version of Pulumi used in the Node provider.

Link to relevant section of the Makefile template:

ci-mgmt/provider-ci/internal/pkg/templates/bridged-provider/Makefile

Lines 352 to 366 in f515e55

	# Because some codegen depends on the version of the CLI used, we install a local CLI
	# version pinned to the same version as `provider/go.mod`.
	#
	# This logic compares the version of .pulumi/bin/pulumi already installed. If it matches
	# the desired version, we just print. Otherwise we (re)install pulumi at the desired
	# version.
	.pulumi/bin/pulumi: .pulumi/version
	@if [ -x .pulumi/bin/pulumi ] && [ "v$$(cat .pulumi/version)" = "$$(.pulumi/bin/pulumi version)" ]; then \
	echo "pulumi/bin/pulumi version: v$$(cat .pulumi/version)"; \
	touch $@; \
	else \
	curl -fsSL https://get.pulumi.com | \
	HOME=$(WORKING_DIR) sh -s -- --version "$$(cat .pulumi/version)"; \
	fi

I'm going to classify this as a bug, in the context of node-based providers.
