bug: suffixes in literals are wrongly parsed

[nik-rev]

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

Literal expressions can have any suffix. https://doc.rust-lang.org/reference/expressions/literal-expr.html

For example, this is valid Rust:

fn main() {
    assert_eq!(100d + 11h + 8m + 7s, DURATION);
}

The culit makes use of this feature to let users define custom literals.

We should have a separate node for the suffix and the body, so we can color the suffix differently, e.g. 100years with 100 being color A and years being color B

String literals, char literals, float literals, integer literals support custom suffixes.

Steps To Reproduce/Bad Parse Tree

For 100d + 100h I got:

(binary_expression
  left: (integer_literal)
  (ERROR
    (identifier)) "+"
  right: (integer_literal))
  (ERROR
    (identifier))

Expected Behavior/Parse Tree

but I expected something like:

(binary_expression
  left: (integer_literal (suffix)) "+"
  right: (integer_literal (suffix)))

Repro

fn main() {
    100d + 100h
}
