Description

If you're changing environments a lot it's easy to make mistakes where you think you're in one environment but you're actually in another. It would be nice if there were a startup option that would change the Julia prompt to include the current active environment, so it would look like this:

(@v1.4) julia>

or this:

(Example.jl) julia>

Contributor guide

Research direction
Investigate how startup options are parsed in Julia's REPL, specifically the mechanism for customizing the prompt. Look for existing options like ` banner` and ` color` to understand the pattern. Then modify the prompt function to include the current active environment when a new startup option is set.
