Suggest replacing braces for brackets on array-esque invalid block expr
Newcomers may write `{1, 2, 3}` for making arrays, and the current error message is not informative enough to quickly convince them what is needed to fix the error.
This PR implements a diagnostic for this case, and its output looks like this:
```text
error: this code is interpreted as a block expression, not an array
--> src/lib.rs:1:22
|
1 | const FOO: [u8; 3] = {
| ______________________^
2 | | 1, 2, 3
3 | | };
| |_^
|
= note: to define an array, one would use square brackets instead of curly braces
help: try using [] instead of {}
|
1 | const FOO: [u8; 3] = [
2 | 1, 2, 3
3 | ];
|
```
