jaawerth c945922b22 command-not-found module: add support for homebrew >= 4.6.12
As of Homebrew 4.6.12, command-not-found is built into Homebrew core and
the tap is deprecated, causing Homebrew to print deprecation warnings on
init until the tap is uninstalled, after which prezto can't find the
helper in its new location.

* Added logic to look first in the new location for handler.sh in the
  core Homebrew repository, *then* check in Taps.
* Added an OSTYPE check for MacOS to prevent this from accidentally
  engaging on Linux systems using Homebrew as a third party package
  manager

# Command-Not-Found
When you try to use a command that is not available locally, searches the
package manager for a package offering that command and suggests the proper
install command.
Debian and Arch Linux based distributions use the [`command-not-found`][1] tool.
macOS uses Homebrew's [`command-not-found` clone][2]. This module will
automatically load it without needing to manually source `handler.sh` from
`.zshrc` per the [instructions][3].
Note: Prior to [Homebrew 4.6.12][4], you may have also needed to tap the
[`command-not-found` Homebrew repository][5]. This will still work as a
fallback when the `command-not-found` handler can't be detected in Homebrew
core, but the repository has been deprecated and may print a warning. After
upgrading Homebrew, it can be untapped.
