[Improvement] Initial value for input

[Squirreljetpack]

pub fn prompt_tags(_initial: &[String]) -> io::Result<Vec<String>> {
    let res: String = cliclack::input("Enter tags (one per line):")
        .multiline()
        .validate_interactively(|s: &String| {
            for (i, line) in s.lines().enumerate() {
                if line.is_empty() {
                    return Err(format!("line {} is empty", i + 1));
                }
                if !line.is_ascii() {
                    return Err(format!("line {} contains non-ascii characters", i + 1));
                }
            }
            // .initial_input(&initial.join("\n"))
            Ok(())
        })
        .interact()?;
    
    Ok(res.lines().map(|s| s.to_string()).collect())
}

example use case ^: would allow editing with input.
I imagine it would override placeholder and default_value if nonempty.

it's a nice to have on a project of mine so very low priority for me to fork and implement currently, but if it fits the theme of the project id be interested in bumping it up and submitting a pr.

@Squirreljetpack I see, it makes sense. It would be like an "editable default value". Although, indeed, it's not of a very high priority.
