promise/always-return should not be reported when process exits

[nandi95]

Description

If I do process.exit(0); in a .then callback no return value should be expected from the callback as after the exit the rest of the code is unreachable.

Steps to Reproduce

 void fetch(
     'my-url',
     {
         method: 'POST',
         headers: {
             // eslint-disable-next-line @typescript-eslint/naming-convention
             'Content-Type': 'application/json'
         },
         body: JSON.stringify({...})
     }
     // eslint-disable-next-line promise/always-return (this should not be needed)
 ).then(() => {
     task.stop();
     process.exit(0);
});

Expected behavior: not to report issue when process exists

Actual behavior: issue reported

I think you should use eslint-plugin-n with process-exit-as-throw.
If you do then something probably is wrong 🤔

But, I am not sure that this should be in the promise plugin.
