Subject: [PATCH] feat: get keyring backend (#11484)

## Description

This PR introduces a getter for the keyring backend type used in the keyring config. This is useful to disable endpoints whenever the keyring `test` backend is used. This is a workaround since the SDK keyring dependency doesn't support locking accounts. See https://github.com/99designs/keyring/issues/85 for context.

Attack on ethereum that affects Ethermint chain validators/nodes using `keyring_backend=test`, making their funds remotely accessible via `eth_sendTransaction`
