bug: Incorrect parsing of attributes

[wetneb]

Did you check existing issues?

• I have read all the tree-sitter docs if it relates to using the parser
• I have searched the existing issues of tree-sitter-rust

Tree-Sitter CLI Version, if relevant (output of tree-sitter --version)

Describe the bug

This grammar successfully parses the following code:

mod tests {
    pub fn execute() {}
    #[cfg(feature = "tracing")]
}

This code is incorrect because #[cfg(feature = "tracing")] is an outer attribute, which needs to be followed by the element it is applied to. This is indeed rejected by rustc:

error: expected item after attributes
 --> test.rs:3:5
  |
3 |     #[cfg(feature = "tracing")]
  |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^

error: aborting due to 1 previous error

A correct version would be:

mod tests {
    #[cfg(feature = "tracing")]
    pub fn execute() {}
}

In this example, we expect the attribute and function declaration to be bundled together, and not treated as two independent children of the module, as is currently the case.

Steps To Reproduce/Bad Parse Tree

See above.

Expected Behavior/Parse Tree

Correctly bundling outer attributes with the syntactic element they apply to.

Repro

mod tests {
    pub fn execute() {}
    #[cfg(feature = "tracing")]
}
