On September 12, 2023, AWS will no longer maintain the Homebrew installer for nightly version of AWS SAM CLI (aws/tap/aws-sam-cli-nightly). For AWS supported installations, use the first-party installers (https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/manage-sam-cli-versions.html#manage-sam-cli-versions-nightly-build).
