Add example of reading script from stdin using echo

[skykasko]

As a non-shell-wizard, I was unfamiliar with the EOF syntax used in the existing example (just above the one I added). I thought including an example where the output of echo is piped to uv run might be more accessible. As a bonus, it should work across more shells: the EOF example doesn't work in fish because fish doesn't support heredocs, while the echo example does.

Feel free to ignore if unwanted.

Maybe we should just show this as a one-line, e.g. $ echo 'print("hello world!")' | uv run - with "console" instead of "bash" syntax? I'd even show this first, then say something like... "Or, if your shell supports heredocs:"

That sounds fine to me. My first thought had been to write it as a one-liner, but then I figured that the reason for the way the existing example was written was that most scripts users might want to run would have multiple lines, so the example should make it easy to add more lines to the script. But your suggestion is cleaner, and users can easily convert the one-liner to a multi-liner, so I'll make the change you suggested.

great addition @skykasko, totally didnt even think when adding the EOF example that echo pipe would also work!
