Replace Marshaler with Codec to mimic CosmosSDK patterns.

[fmorency]

Describe the bug
I was playing with the Rosetta 1 integration and realized there is a params/encoding.go discrepancy between Ignite and CosmosSDK.

The EncodingConfig struct found in ignite/templates/app/files/app/params/encoding.go.plush should be changed from

type EncodingConfig struct {
	InterfaceRegistry types.InterfaceRegistry
	Marshaler         codec.Codec
	TxConfig          client.TxConfig
	Amino             *codec.LegacyAmino
}

to

type EncodingConfig struct {
	InterfaceRegistry types.InterfaceRegistry
	Codec             codec.Codec
	TxConfig          client.TxConfig
	Amino             *codec.LegacyAmino
}

to match the CosmosSDK pattern.

Relates cosmos/cosmos-sdk#17608

Thank you for reporting this issue, @fmorency 🙌

I appreciate you bringing this discrepancy to our attention. I've reviewed the problem, and you're absolutely right. To align with the CosmosSDK pattern, we need to make the change you've suggested in the EncodingConfig struct.

I'm currently working on a new pull request to address this issue, and I'll keep you updated on its progress. If you have any additional insights or suggestions related to this, please feel free to share them.

Once again, thank you for your contribution to the project! 🚀
