Merge branch 'alic/binding_lint' into 'master'

chore: Enable linting error for `bindings_with_variant_name`

Reference for the lint: https://doc.rust-lang.org/beta/nightly-rustc/rustc_lint/builtin/static.BINDINGS_WITH_VARIANT_NAME.html

This lint is currently only a warning on our current Rust version. I recommend turning it into an error. The failure can be quite nasty. Consider this example:

```Rust
pub enum PayloadType { Summary, Data }

// ... later somewhere
let x = PayloadType::Data;
match x {
    Summary => println!("summary"),
    Data => println!("data"),
}
```
Now, in the ic repo, the above code will print "summary", because without the fully-qualified path, Summary is just a bound variable (instead of a sum type variant)

**This lint is deny-by-default since Rust 1.68.2 ([this MR](rust-lang/rust#104154)), but we're still on an older version. That's why I suggest we enable it pro-actively.**
