doc: remove extensionless CJS exception for type:module packages

Remove the documented exception that extensionless files in
type: "module" packages are recognized as CommonJS when included
via require(). This exception conflicted with the ESM resolution
specification which states that extensionless files within a
package scope with an explicit type field follow the format of
the type field.

The behavior on main already matches the ESM spec since #61600,
this change aligns the CJS documentation accordingly.
