fix(security-insights): set filtered table data on initial load

[pc-bob]

This PR updated this component to filter to open on initial load. However, on initial load only tableData was being set previously.

Fixes: #1492

There is a check in the JSX to render filteredTableData if insightsStatusFilter is set. Since insightsStatusFilter is set with the default state value now (const [insightsStatusFilter, setInsightsStatusFilter] = useState<SecurityInsightFilterState>('open');), this was rendering filteredTableData on the first render which was null. Clicking on Open would display data but may give uses a false sense of security that they have no security insights with a quick glance at the tab.
