CLI install overwrites /usr/local/bin if directory does not exist

[mdierolf]

When installing the CLI using the installer, if /usr/local/bin does not exist, the binary is written as a file called /usr/local/bin instead of creating the /usr/local/bin directory, and the installation fails

# rm /usr/local/bin 

# ls -la /usr/local/bin
ls: cannot access '/usr/local/bin': No such file or directory

# curl -fLSs https://raw.githubusercontent.com/CircleCI-Public/circleci-cli/main/install.sh | bash

# ls -la /usr/local/bin
