Actually support query logging

[gwynne]

These changes are now available in 4.9.0

Now supports query logging with the same semantics as the other drivers. When a query is executed with query logging enabled at or above the logger's current log level, the actual SQL query and its accompanying array of bound parameters (if any) are logged as structured metadata on the logger using a generic message. This follows the recommended guidelines for logging in libraries. Credit goes to @MahdiBM for the original suggestion.

Before:

2024-05-29T00:00:00Z debug codes.vapor.fluent : database-id=mysql [MySQLKit] SELECT * FROM foo WHERE a=? [["bar"]]

After:

2024-05-29T00:00:00Z debug codes.vapor.fluent : database-id=mysql sql=SELECT * FROM foo WHERE a=? binds=["bar"] [MySQLKit] Executing query

Also bumps dependency minimums.
