CKAN plugin does not support brotli encoding

[psiotwo]

1. CKAN plugin calls the SPARQL endpoint with Accept-encoding: gzip, deflate, br (defaults of the http client used).
2. CKAN plugin receives Content-encoding: br but can't decompress it.

Error from logs:

docker logs lindas-test

Error: Decompression failed
at genericNodeError (node:internal/errors:983:15)
at BrotliDecoder.zlibOnError [as onerror] (node:zlib:190:17)

Tested locally:

1. Trifid run with updated node_modules/lindas-trifid-plugin-ckan/src/ckan.js
2. Test CKAN endpoint:
