squawk: Specify PostgreSQL version in config (#28094)

Finn Evers created

This PR adds the PostgreSQL version to the squawk config, see
https://squawkhq.com/docs/cli#specifying-postgres-version for reference.

The specified version matches the PostgreSQL version in the compose-file


https://github.com/zed-industries/zed/blob/43cb925a599ead7ddbeee26efd1f5af1d1dea97a/compose.yml#L3

and prevents false positives like
https://github.com/zed-industries/zed/pull/28090#issuecomment-2778871346
from happening (tested it locally with that commit).
