Remove internal fields from alert details table

What does this MR do?

The alert detail table shows internal alert fields. This is because it displays anything that was returned from the AlertManagementAlert api call.

These additional fields are used for other functionality on the page, so cannot be removed from the query. Instead, we should filter the alert data to show only desired fields in the table.

Changes:

• add a filter for desired alert detail fields to the table component.
• remove filtering from usage of this table in the incident page, since this functionality is now performed by the alert detail table component.
