Support for Node v16

[anudit]

Could we upgrade @vercel/build-utils to 2.17.0 from 2.12.1 to support the new Node 16 runtime?

Running into the following error currently,

Hi, yes Node 16 runtime support is on the radar, but takes a few extra steps besides just upgrading the @vercel/build-utils dependecy:

• Upgrade sammy: Add support for nodejs16.x runtime sammy#13
• Upgrade @vercel/build-utils
• Set default runtime to nodejs16.x in variables.tf
• Wait for Terraform AWS Provider v4.15.0 to be released (Feature Request: nodejs16.x support for aws_lambda_function hashicorp/terraform-provider-aws#24714, build(deps): bump github.com/aws/aws-sdk-go from 1.44.10 to 1.44.13 hashicorp/terraform-provider-aws#24768)

Support for the Lambda runtime nodejs16.x is tracked here: #316

Oh, misinterpreted your issue.
You are asking for Node.js 16 support for the CLI not the nodejs16.x runtime 🙈

[ofhouse]

However I think setting the "engines": { "node": "14.x" } field in your package.json is the right solution here.
The CLI should still build fine with Node.js 16, but since we currently don't support the nodejs16.x runtime, it does not make sense to allow the creation of Lambdas with Node.js 16 as target.

This has been fixed in v0.13.0.
