Kadena (and Ethereum) light-client instructions are not correct

Following the Kadena light-client instructions results in error as the package is called `kadena-lc`

https://argumentcomputer.github.io/zk-light-clients/kadena/run/setup_client.html#launch-the-client

```
MODE=SNARK RUST_LOG="debug" cargo run -p light-client --release --bin client -- -c https://api.chainweb.com -p localhost
error: package(s) `light-client` not found in workspace `/Users/rsoeldner/repo/kadena/zk-light-clients/kadena
```

Open the Kadena setup page at run/setup_client.html#launch-the-client and compare its documented cargo command with the reported workspace package name, kadena-lc. Update the incorrect instruction and verify that the command names the available package; the issue also mentions Ethereum instructions, but gives no further details to investigate.
