build: add ijson as a runtime dependency

Adds the ijson streaming JSON parser as a direct dependency so connectors that
ship inside the source-declarative-manifest base image can stream-parse very
large JSON response bodies without materializing the full document in memory.

Motivation: source-amazon-seller-partner currently OOMs while reading
GET_BRAND_ANALYTICS_SEARCH_TERMS_REPORT documents that can exceed 3 GB
uncompressed. See airbytehq/oncall#12143.
