Fix verify_in_ssl log statement which no longer has access to SSL params (#202)

## Ticket

#200

## Changes

Removes log statement that relies on variables no longer in psycopg 3.

## Context for reviewers
The upgrade to psycopg3 got this error during migrations:
`AttributeError: 'ConnectionInfo' object has no attribute
'ssl_attribute_names'` -
https://github.com/navapbc/platform-test-flask/actions/runs/6275581568/job/17043454952

These aren't available anymore and looking through the connection info
object, I don't see any equivalent. Looking at the docs for version 2,
these attributes say `Only available if psycopg was built with libpq >=
9.5`
https://www.psycopg.org/docs/extensions.html#psycopg2.extensions.ConnectionInfo.ssl_attribute

While the docs for psycopg3 mention libpq as being the backing library
it uses, I don't see any mention of these parameters in their docs.
https://www.psycopg.org/psycopg3/docs/api/connections.html#psycopg.Connection.pgconn
- so seems to just be gone entirely?

## Testing
