Problem: (fix crypto-org-chain#88) missing docs for check-validator-u…

…p.sh when node is using tmkms in the background

Solution: add description for check-validator-up.sh usage and fix check-validator-up.sh

 To further check if the validator is signing blocks, kindly run this [script](https://github.com/crypto-com/chain-docs/blob/master/docs/getting-started/assets/signature_checking/check-validator-up.sh), for example:
 
 ```bash
-$ ./check-validator-up.sh --tendermint-url https://testnet-croeseid.crypto.com:26657 --pubkey $(cat ~/.chain-maind/config/priv_validator_key.json | jq -r '.pub_key.value')

+For those who are using tmkms in background([AWS](./testnet-aws-1click.html)/[Azure](./testnet-azure-1click.html) 1-click deployment are using tmkms), you should use `--bechpubkey` the consensus pubkey with prefix `tcrocnclconspub1....` directly instead of `--pubkey` tendermint pubkey since the node is not using `~/.chain-maind/config/priv_validator_key.json` for signing.
