Describe the bug
Bugs in Tool recommendation API call and its associated UI

Galaxy Version and/or server at which you observed the bug
Galaxy Version: release_23.0 (https://github.com/galaxyproject/galaxy/tree/release_23.0)

To Reproduce
Steps to reproduce the behavior:S1_File_ Transformer-based-tool-recommender.pdf

1. Enable tool recommendation feature - In Galaxy.yml file, set enable_tool_recommendations to true, and uncomment tool_recommendation_model_path and topk_recommendations attributes.
2. Upload a tabular file and run a tool such as Sort data in ascending or descending order
3. The tool recommendations section in the Galaxy's central panel show the following error - Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '0') at VueComponent.renderD3Tree (ToolRecommendation.vue?9b7c:72:1) at eval (ToolRecommendation.vue?9b7c:60:1)
4. Further, in the workflow editor, hover action on tool recommendation icon on any toolbox (right arrow) does not call its API (https://github.com/galaxyproject/galaxy/blob/release_23.0/lib/galaxy/webapps/galaxy/api/workflows.py#L598).
5. Similar issues persist in Galaxy EU in the newest release (release_22.05_eu)

Expected behavior
For the 3rd point, a tree should be shown with recommendations.

For the 4th point, a popover should be shown with a list of recommendations.

ping @dannon thank you!

I looked into it a bit and found that in the file client/src/components/Workflow/Editor/Node.vue at

<Recommendations
       v-if="popoverShow"
       :step-id="id"
       :datatypes-mapper="datatypesMapper"
       @onCreate="onCreate" />

if v-if="popoverShow" is removed, the recommendations work fine in the workflow editor (image below)

But, in Galaxy's central panel where recommendations are shown after any tool execution as a D3.js tree, it needs a lot of work - probably the entire JS script should be rewritten in the latest version of D3.js. I made changes locally in release_23_0 branch.

Any suggestions @dannon thanks!
