Issues about channel (version?) property in `rust-toolchain`

[minstrike520]

Environment

• proot-distro arch linux in termux
• CPU structure: aarch64

  How to recreate

  1. Use the template on https://github.com/emilk/eframe_template (master, 96e4908b1c7ba2da6c0527589e5f6e3060f93ee9)
  2. Clone the repo
  3. Use cargo command, then the following message:

     
     error: the 'cargo' binary, normally provided by the 'cargo' component, is not applicable to the '1.76.0-aarch64-unknown-linux-gnu' toolchain

Stack backtrace: 0: 1: 2: 3: 4: 5: 6: 7: 8: __libc_start_main 9:

## How to solve
Just edit file `rust-toolchain` :
```toml
[toolchain]
-channel = "1.76.0"
+channel = "1.76"

Then cargo can run successfully.

Description

Although it's just a minor difference from before and after the fix, the problem can cause the whole project not working. I don't know if this problem only happens on my device, so I'm not sure if this counts as a bug or not. Could someone provide further information?
