Duplicate Definition Error in `define_unknown_imports_as_traps` Method

Test Case

// omit ...
linker
    .define_unknown_imports_as_traps(&component_a)
    .unwrap();
let ins_a = linker.instantiate_pre(&component_a).unwrap();
let ins_a = ins_a.instantiate(store_a.as_context_mut())?;
linker
    .define_unknown_imports_as_traps(&component_b)
    .unwrap();
let ins_b = linker.instantiate_pre(&component_b).unwrap();
let ins_b = ins_b.instantiate(store_b.as_context_mut())?;

Steps to Reproduce

Call the define_unknown_imports_as_traps method multiple times in the same linker.

Expected Results

The method should handle multiple calls without causing duplicate definitions for any module.

Actual Results

The method results in a duplicate definition error for the wasi module.

map entry `wasi:cli/environment@0.2.0` defined twice

Extra Info

Possible Solutions:

Exclude Specific Entries: Modify the method to exclude specific entries like wasi from being redefined.

I think it's not a bug at all, but I can't handle it by myself.
