Ron Lusk b821ffdd33 docs(move_semantics5): Replace "in vogue" with "in scope" in hint 
The hint for `move_semantics5` refers to "the range in which each
mutable reference is in vogue". Unless this is a deliberate
introduction of "vogue" (an admittedly-useful term because "scope"
isn't purely lexical, as in many other languages), it may be in error:
I have been unable to find the term used with reference to *Rust*
references.

Thus, I'm suggesting the replacement, in case it's been overlooked.

chore: Update hint of iterators3 
`collect()` needs some hint for standard_library_types/iterators3 exercise with doc link for understanding different return types via `FromIterator`.

Taylor Yu 2dc93cadda fix(from_str, try_from_into): custom error types 
Remove the use of trait objects as errors from `from_str` and
`try_from_into`; they seem to have caused a lot of confusion in
practice. (Also, it's considered best practice to use custom error
types instead of boxed errors in library code.) Instead, use custom
error enums, and update hints accordingly. Hints also provide
some guidance about converting errors, which could be covered
more completely in a future advanced errors section.

Also move from_str to directly after the similar exercise `from_into`,
for the sake of familiarity when solving.

Taylor Yu b7ddd09fab address review feedback 
Adjust error text and naming to conform with best practices.
Use `map_err()` instead of `or()`. Wrap lower-level errors instead of
ignoring their details.

Also, don't "cheat" by bypassing the `new()` function in tests.

Fix a dangling reference in the try_from_into hints.

Taylor Yu 68d3ac567c feature: improve error_handling exercises

too much too soon.

Taylor Yu 1b85828548 fix: move_semantics5 hints 
Improve the hints for move_semantics5, as well as the explanatory
comments in the code.

Previously, it was not clear what possible changes were allowed.
It seems that reordering the statements might be the intended solution.
The previous comment about not "adding newlines" doesn't make sense,
so treating it as "adding new lines" makes it more clear.
