7894: generate_function assist: convert arg names to lower snake case r=Veykril a=JoshMcguigan

This PR fixes one of the points listed by @TimoFreiberg in #3639. Specifically that all generated argument names should be converted to lower snake case. 

```rust
struct BazBaz;

fn foo() {
    bar$0(BazBaz);
    // ^ when triggering the assist here, you get the output below
}

// BEFORE
fn bar(BazBaz: BazBaz) ${0:-> ()} {
    todo!()
}

// AFTER
fn bar(baz_baz: BazBaz) ${0:-> ()} {
    todo!()
}
```
