esm: use import attributes instead of import assertions

The old import assertions proposal has been
renamed to "import attributes" with the follwing major changes:

1. The keyword is now `with` instead of `assert`.
2. Unknown assertions cause an error rather than being ignored,

This commit updates the documentation to encourage folks to use the new
syntax, and add aliases for module customization hooks.
