Many of our flutter_tools templates include image assets such as
application icons. Adding these will trigger an analysis error from our
CI tooling.

This adds a pointer to the wiki describing the procedure for adding or
updating image assets in the templates:

Uncovered while working on https://github.com/flutter/flutter/issues/103371

Until recently, BuildInfo.packagesPath defaulted to `.packages` however,
the .packages file has been deprecated [1] and is being removed. In
https://github.com/flutter/flutter/pull/99677 the default was changed to
`.dart_tool/package_config.json` but the doc comment was accidentally
updated to `.dart_tool/packages`. This corrects it to the true default
value.

stack overflows depending on their implementation.
