Description of your changes

Added cleanup step to remove temporary AWS CLI installation files (/aws and /tmp/awscliv2.zip) after installation, reducing the final image size. This also addresses some AWS CLI permissions when setting a different UID/GID.

Testing

Ran locally using UID/GID 2000:

$ docker run -it --rm --user 2000:2000 --entrypoint /bin/zsh index.docker.io/steve/function-shell:permfix 
0467ea58ba81% id
uid=2000 gid=2000 groups=2000
0467ea58ba81% aws sts  get-caller-identity
{
    "UserId": "xxx:steven@example.com",
    "Account": "abc",
    "Arn": "arn:aws:sts::abc:assumed-role/1234/steven@example.com"
}
