Problem: No suggestion for RPC error -32603 in the docs

The issue:
A common error message
`Error: RPC error -32603 - Internal error: timed out waiting for tx to be included in a block`
sometimes pop up especially for larger txs such as fetching rewards/restaking.

**Suggestion**:
- Adding `--timeout-height` flag ( Thanks @leejw51crypto );
- Adding `--gas-prices `flag for fee adjustment.

Search the documentation for transaction commands and the references to --timeout-height and --gas-prices. Confirm the -32603 timeout scenario is explained and that both suggested flags are documented with enough guidance to address larger transactions.
