[Guided Setup] - Add a tool to import a default tree

[CarolineDenis]

Proposed Enhancements:

1. Fetching Tree List from AWS Bucket

• The default trees will be stored in an AWS bucket, and the backend will pull the data from there.

• A list of default trees, including their descriptions and sources, will be dynamically generated on the frontend by fetching a remote JSON file from https://files.specifysoftware.org/taxonfiles/taxonfiles.xml.

• The existing XML file needs to be converted to JSON format for compatibility.

2. Displaying Tree List in UI

• When the user clicks the "+" button in the tree viewer, a dialog will appear displaying the dynamically fetched list of trees.

• Upon clicking a tree, the tree data will be uploaded to the database.

3. Rank Management Enhancements

• Users can continue to edit and remove ranks using the existing rank editor.

• Users can remove sections of the tree by deleting the oldest parent node, which will remove all its child nodes as well.

Dependent issue to manage the ranks:
