docs: update SMTP configuration in notifications docs (#17161)

## Issue

Closes #16206

(thanks @bjornrobertsson - not sure why I can't tag you as a reviewer)

Mismatch between the SMTP configuration UI and the documentation.

## Verification

Claude verified this issue by examining:

1. The current SMTP configuration code in the codebase
2. The CLI help documentation for the server command
3. The examples provided in the notifications documentation

The issue was confirmed by finding:
- A reference to a deprecated variable
`CODER_NOTIFICATIONS_EMAIL_FORCE_TLS` instead of the current
`CODER_EMAIL_FORCE_TLS`
- Missing information about the port format required for the SMTP
smarthost

## Changes made

1. Updated the `--email-smarthost` description to clarify that the
format should include both hostname and port: `(format:
     hostname:port)`
2. Fixed the reference to the TLS environment variable in the STARTTLS
description, replacing the deprecated
`CODER_NOTIFICATIONS_EMAIL_FORCE_TLS` with the correct
`CODER_EMAIL_FORCE_TLS`

## Additional information

The Gmail and Outlook examples in the documentation already correctly
show the port included in the smarthost configuration, but the main
description table needed to be updated to explicitly mention this
requirement.
