fixing doctest failures in resurfaced extended information

After repatriating error explanations to the global registry, some lurking
doctest failures surfaced and needed to be chased down. Sadly, a few doctests
needed to be ignored due to a not-yet-understood regression in the doctest
`compile_fail` functionality (filed #43707).

 Erroneous code example:

 ```
 
 An inclusive range needs an end in order to *include* it. If you just need a
 start and no end, use a non-inclusive range (with `..`):
 
 ```
-let tmp = vec![0, 1, 2, 3, 4, 4, 3, 3, 2, 1];
-let x = &tmp[1..]; // ok!
+fn main() {
+    let tmp = vec![0, 1, 2, 3, 4, 4, 3, 3, 2, 1];
+    let x = &tmp[1..]; // ok!
+}
 ```
 
 Or put an end to your inclusive range:
 
 ```
-let tmp = vec![0, 1, 2, 3, 4, 4, 3, 3, 2, 1];
-let x = &tmp[1...3]; // ok!
