Template: remove useless code from the module template

[fadeev]

Remove the RegisterCodec function from module.go.

cli/ignite/templates/module/create/stargate/x/{{moduleName}}/module.go.plush

Lines 49 to 51 in 0453e26

	func (AppModuleBasic) RegisterCodec(cdc *codec.LegacyAmino) {
	types.RegisterCodec(cdc)
	}

RegisterCodec has been renamed to RegisterLegacyAminoCodec (which we already have in the template) a long time ago, so it's just purely unnecessary.

Remove RegisterRESTRoutes. It has been deprecated and is no longer used in the new v0.46 app.go template.

cli/ignite/templates/module/create/stargate/x/{{moduleName}}/module.go.plush

Lines 76 to 78 in 0453e26

	// RegisterRESTRoutes registers the capability module's REST service handlers.
	func (AppModuleBasic) RegisterRESTRoutes(clientCtx client.Context, rtr *mux.Router) {
	}

Comments in the template mention the capability module, which might confuse new devs. Those should be removed as well.

Sorry, it has a PR already associated with it.
