Make it more obvious how to submit tickets during the login workflow

Rationale

There have been a few reports of users contacting support@posthog.com when facing login issues, which is not a monitored inbox. The goal is to prevent customer frustration and improve the support experience by making it more obvious how to submit tickets during the login workflow.

What we'll ship

Implement a more obvious prompt to the user for how to submit a support ticket.

We'll know we're successful when

We don't cause frustration to users attempting to contact us and we get fewer tickets with the email-closed tag that have been created due to issues encountered during the login workflow.

Stretch goals

Identify opportunities to triage tickets with the email-closed tag for login (and potentially billing) issues.
