Fix typo and clarify PGPASS_FILE documentation (#9866)

[dpage]

Summary

Fixes #9866.

The container deployment docs for PGPASS_FILE had a typo ("varible") and an incomplete sentence ("should be set to if you want to..."). Reworded to explain that the variable is the path to a pgpass file that is copied into the container (per pkg/docker/entrypoint.sh) and used as the .pgpass file.

Docs-only change; no release note.
