Remove commands available in the top-level from the suggested subcommand error (#8316)
Part of https://github.com/astral-sh/uv/issues/8313
I think we'll need to open an issue upstream to add more context to the
error here, because there's not sufficient information about the parent
command to provide a good error message. As a first step, let's avoid
giving these suggestions for subcommands that overlap with our top-level
commands.. because that's just confusing.
Here's all the information we have here
```rust
[crates/uv/src/lib.rs:1530:13] &err = ErrorInner {
