Add `--outdated` for `rye tools list` to display outdated tools

I use rye tools install to install lots of tools, and I wonder to know how many tools are outdated, and upgrade these tools. Thanks.

Specifically, for my use case, I'd want this to behave similar to npm outdated. In other words, give my the current (installed), wanted (constrained by any version specifiers), and latest (latest published to pypi regardless of version specifiers) versions available.

@linux-china is this your use case as well?

npm oudated is good for me. :)
