Detect swallowed errors when re-throwing in Promise `catch` handlers

[Amnish04]

Currently, we only look for swallowed errors in synchronous operations within catch blocks.

We need to extend the no-swallowed-error-cause rule to handle cases where a new error is being thrown in catch handlers of promises.

Here's an example:

new Promise((resolve, reject) => {
    throw new Error("Failing because...");
}).catch((error) => {
    // `error` is getting swallowed
    throw new Error("Something went wrong");
});

Closing this as rule has been integrated into core ESLint and this repo will no longer be maintained!
