Tech Debt: Configure testing of `*.tsx` files

[alexec]

Summary

We should be able to test tsx files.

Motivation

To improve the code quality.

Proposal

Not sure, need to fix this error:

    TypeScript diagnostics (customize using `[jest-config].globals.ts-jest.diagnostics` option):
    src/app/applications/components/utils.test.ts:1:33 - error TS6142: Module './utils' was resolved to '/Users/acollins8/go/src/github.com/argoproj/argo-cd/ui/src/app/applications/components/utils.tsx', but '--jsx' is not set.
