Updates to RAI text dashboard - update test app values to latest shap release, fix predicted label, limit selection to one row, fix random crash

[imatiach-msft]

Description

This PR includes several small updates and bug fixes to the RAI text dashboard after manual testing:
1.) Update the predicted probabilities and local feature importance values to the latest shap package version update in the test app (which also changed the predicted values to be probabilities instead of raw values).
2.) Fix predicted label being incorrectly shown as the lowest instead of highest probability label.

3.) Limit selection of instances to a single instance in text case, unlike tabular case which has comparisons enabled.
4.) Fix random crash due to text and importances length getting out of sync in intermediate render calls when clicking on different rows to view different local importances

Checklist
