fix(smtp): inject SMTP password secret via entrypoint, not *_FILE

The official discourse/discourse image has no *_FILE support, so
DISCOURSE_SMTP_PASSWORD_FILE was silently ignored and SMTP auth booted
without a password. Read the secret in the wrapper entrypoint and export
DISCOURSE_SMTP_PASSWORD, mirroring the DB password handling. Bump
APP_ENTRYPOINT_VERSION so the new entrypoint config redeploys.

Add release notes for the bitnami->official SMTP env var renames.

+This release switches from the bitnami image to the official discourse/discourse
+image. Some env vars need to be renamed for this migration; everything else
+should happen automatically.
+
+Rename these in your app's .env (the values carry over):
+
+  DISCOURSE_SMTP_HOST     --> DISCOURSE_SMTP_ADDRESS
+  DISCOURSE_SMTP_USER     --> DISCOURSE_SMTP_USER_NAME
+  DISCOURSE_SMTP_AUTH     --> DISCOURSE_SMTP_AUTHENTICATION
+  DISCOURSE_SMTP_PROTOCOL --> DISCOURSE_SMTP_ENABLE_START_TLS
+
+Note: DISCOURSE_SMTP_ENABLE_START_TLS takes a boolean (true/false), not the old
+tls/ssl value, so translate it rather than copying it straight across.
