Webpush gem throws errors such as `WebPush::ExpiredSubscription`,
`WebPush::InvalidSubscription`, `WebPush::Unauthorized`. We handled only
ExpiredSubscription.
If the SDK threw any other errors, it would pause sending the
notification to all other devices for that user. This change would
update the logic to remove the expired subscription and handle the rest
of the errors gracefully.

- The previous gem, `webpush` was last updated a while ago. Also, with the recent ruby upgrade, we needed a fix for zaru/webpush#106. Hence switching to the `web-push` gem where the issues are fixed.
