Attempts a solution for #536

It seems as though @aws-sdk/client-cloudformation is no longer compatible with Node <16. Do the checks need to be updated to remove 14 and this be declared a breaking change? Or is there some other path for this to proceed?

Thanks for confirming.

First, the fact that the test fails with Node 14 has nothing to do with the esbuild version update.

The cause is the end of support for Node.js 14.x in aws-sdk-js-3 issue #6034.
Therefore, since the release of aws-sdk-js-3 v3.567.0 which includes #6034, tests for Node.js 14 will fail.

Do the checks need to be updated to remove 14 and this be declared a breaking change?

Since Node.js 14 is not listed in the supported runtimes, I think supporting Node.js 16 and 18 is sufficient.

Should we create an issue for end support for Node.js 14.x?
