Frontend taxonomy UI needs to handle new `is_default` field

[allisonking]

Is your feature request related to a specific problem?

https://github.com/ethyca/fides/pull/976 adds an is_default field to taxonomy. Editing taxonomy fields (https://github.com/ethyca/fides/pull/977) may not work as expected due to the additional field.

Describe the solution you'd like

• Regenerate openAPI typescript types
• Make sure editing taxonomy fields still work okay

Describe alternatives you've considered, if any

A description of any alternative solutions or features you've considered.

Additional context

Blocked by https://github.com/ethyca/fides/pull/976 merge. This should also be done before https://github.com/ethyca/fides/pull/977 is merged to make sure it'll still work
