[Bug] AptosCoin does not have a paired metadata

[JoeruCodes]

🐛 Bug

According to the documentation it says that for migration reasons all coins automatically have a paired_metadata counterpart, but AptosCoin type doesnt seem to have one when 0x1::coin::paired_metadata is called.

To reproduce

Code snippet to reproduce

    use aptos_framework::aptos_coin::AptosCoin;
    #[test]
    fun test_paired_metadata_for_apt(){
        assert!(option::is_some(&coin::paired_metadata<AptosCoin>()), 1);
    }

Stack trace/error message

┌── test_paired_metadata_for_apt ──────
│ error[E11001]: test failure
│     ┌─ /sources/deployer.move:160:9

Expected Behavior

The assert shouldn't fail and instead of being empty, the option should have the paired metadata of the AptosCoin.

System information

Please complete the following information:

• Aptos 3.5.0
• Move
• PopOS!

This function should create fungible_asset in the coin_conversion_table and may resolve this issue the only problem is that, I can't do it in my smart contract as it requires aptos_framework (0x1) as a signer...

Calling this function in the init_module function in the aptos_coin module should virtually solve this problem

If this is for test, can you see https://github.com/aptos-labs/aptos-core/pull/12028 ? you can all ensure_initialized_with_fa_metadata_for_test before test your own code.
