feat: Add support for large files with declarative nodes

[Joffcom]

Github issue / Community forum post (link here to close automatically): https://community.n8n.io/t/maxbodylenght-limit-with-google-cloud-storage-node/27216

Declarative nodes don't appear to use proxyRequestToAxios() which was updated in 0.179.0 to allow files over 10mb to be uploaded. This PR adds the same option for the newer node style, Tested with a 32mb PDF and a 210mb zip to Google Cloud Storage.

To test...

export N8N_PAYLOAD_SIZE_MAX=400
