SQL: Adjust JDBC docs to use milliseconds for timeouts (#79628)

Resolves #79480

My initial thought was to change the properties to be interpreted as seconds but this might not be worth it. All relevant places in the code seem to assume the timeouts to be in ms and there does not seem to be a consistent use of ms or s across JDBC drivers (Postgres uses seconds, MySQL uses ms, MS SQL mixes the two depending on the connection property).

Hence, just fixing the docs might be easier.
