Fix XLayer Testnet chain configuration - Update chainId from 195 to 1952

[xrqin]

Summary

This PR fixes the XLayer Testnet configuration in the chains registry. The current chainId (195) is incorrect and should be updated to 1952.

Changes Made

• Updated chainId from 195 to 1952
• Updated networkId from 195 to 1952
• Verified RPC endpoint configuration
• Updated chain configuration to match the actual XLayer Testnet deployment

Verification

The correct chain parameters have been verified through direct RPC calls to the XLayer Testnet:

# Chain ID verification
curl -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' \
  https://testrpc.xlayer.tech/terigon
# Result: {"jsonrpc":"2.0","id":1,"result":"0x7a0"} (0x7a0 = 1952)

# Network ID verification  
curl -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"net_version","params":[],"id":1}' \
  https://testrpc.xlayer.tech/terigon
# Result: {"jsonrpc":"2.0","id":1,"result":"1952"}

Context

As maintainers of the XLayer project, we identified that the current chain configuration does not match our actual testnet deployment. This update ensures that users can properly connect to XLayer Testnet using the correct chain parameters.

This change will help developers and users properly connect to XLayer Testnet through wallets and dApps that rely on the ethereum-lists chain registry.

You successfully submitted a PR! Due to the amount of PRs coming in: we will only look at PRs that the CI is happy with. We can also not hold your hand getting the CI green - just look how others that where merged did it and RTFM. So as long as there is any CI check that reports an error - no human will look at this. You might be able to ask for some support after supporting the project - e.g. by sending funds to lists.eth. When you fixed things after a requested change - then you also need to (re-)request a review.
