E0424 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/E0424.rs

E0424 needs a span_label, a note, and an updated title, changing it from:

error[E0424]: `self` is not available in a static method. Maybe a `self` argument is missing?
  --> src/test/compile-fail/E0424.rs:17:9
   |
17 |         self.bar(); //~ ERROR E0424
   |         ^^^^

To:

error[E0424]: `self` is not available in a static method
  --> src/test/compile-fail/E0424.rs:17:9
   |
17 |         self.bar(); //~ ERROR E0424
   |         ^^^^ not available in static method
