This change incorporates to Rails a feature called error_highlight that
has been available since Ruby 3.1. This allow Rails' error report screen
to display the fine-grained location where an error occurred (not only a
line number but also beginning and end column numbers of the code
fragment).

For ErrorHighlight, see https://bugs.ruby-lang.org/issues/17930

 in
detail.

To use error_highlight, ExceptionWrapper now prefers
`Exception#backtrace_locations` (since Ruby 2.1), which returns an array
of `Thread::Backtrace::Location`s, instead of `Exception#backtrace`.
This is because error_highlight requires `Thread::Backtrace::Location`
to locate the column where an error was raised.
