chore: update slack link
Created by: ashleythedeveloper
This PR fixes #244 (closed) by updating the Slack link to improve the user experience and consolidating related configuration.
Previously, two separate links were used: one that led directly to the Slack client (which failed for unauthenticated users) and another that served as an invite link. This PR consolidates both into a single variable slackLink
pointing to the shared invite URL:
https://join.slack.com/t/uncefact/shared_invite/zt-35d2dcrn7-2KEYgff22ob7BtQcprolkg
Note: The previous link has expired. I've created a new long-lived link.
This link handles both new and existing users gracefully, where unauthenticated users are directed to sign up or join the workspace, while authenticated users are taken directly to the appropriate channel.
