fix: notebooks insight bugs

[daibhin]

Problem

Covers two issues pointed out in Slack

1. Timings show up on data table nodes
2. Clicking "Add to notebook" on an insight adds a random insight

Changes

1. Set the showTimings flag to false for data table nodes
2. We rely on the attrs in a resource to create the node. I removed it in fix: show correct badge count on notebook button #17735 to fix a different bug where the search results because the id attr was expected which a query node does not have (only attr is query).

How did you test this code?

Manually
