`uv venv` does not suggest how to activate

[zanieb]

❯ uv venv
Using Python 3.11.7 interpreter at /opt/homebrew/opt/[email protected]/bin/python3.11
Creating virtualenv at: .venv

❯ source .venv/bin/activate

We should prompt activation

[zanieb]

python -m venv is silent; virtualenv is verbose but not helpful

❯ virtualenv foo

@zanieb For prompting activation, would it be sufficient to add the following to crates/uv/src/commands/venv.rs inside of venv_impl?

    writeln!(
        printer,
        "Activate virtualenv: source {}/bin/activate",
        path.normalized_display().cyan()
    )
    .into_diagnostic()?;

Happy to make a small PR/update tests if so.

I think so! Maybe styled like "Activate with source ...."?

Note we also need a separate hint to Windows users
