ON keyword should not throw errors for RPC URLs

[iankressin]

Description

EQL allows users to specify RPC URLs inline instead of using the chain name, but the UI parser is preventing that.

A new rule should be included to make sure URLs are allowed, excepted for the ones containing localhost.

The solution likely involves including a condition in the line below, to ensure URL format is supported

eql-web-repl/src/lib/helpers/parser.ts

Line 401 in 92aad36

if (!chains.some((c) => c.startsWith(chain))) {

Expected result

To not throw erros for queries using inline RPC URLs
GET * FROM account vitalik.eth ON https://custom-rpc.com
