Rustup could show the planned release date for the next version of Rust toolchain

[pcgeek86]

Problem you are trying to solve

Every few days, I fire up a terminal (PowerShell Core) and run rustup check to see if there's a new stable release of the Rust toolchain available. Most of the time, there isn't a release available, and I'm kinda left wondering when I should check again.

Solution you'd like

It would be kinda neat if the rustup check command would indicate the next planned / targeted release of a Rust toolchain update, for stable and beta release channels, at least.

Think of it like "hey, you're up-to-date, but check back in 2 weeks and there will probably be a new stable release!" or "next week there will probably be a new beta of 1.84!"

Notes

I don't think this would be trivial to do for the general case. The stable channel has a very reliable cadence but I'm not sure the same is true for beta and for nightly it feels fairly pointless?

I recommend just putting a repeating 6-week event in your calendar (I have this).
