Runtime errors in unit tests files with the sufix .js that contain JSX

[rmessina1010]

Description

Resolve .jsx parsing issue that is leading to runtime errors in unit tests files with the sufix .js that contain JSX elements.
Example:
Exception during run: SyntaxError[ @/Users/raymessina/Desktop/__store git/vets-website/src/platform/user/tests/authentication/components/SessionTimeoutModal.unit.spec.js ]: Unexpected token '<' at compileSourceTextModule (node:internal/modules/esm/utils:340:16) at ModuleLoader.moduleStrategy (node:internal/modules/esm/translators:102:18) at ModuleLoader.#translate (node:internal/modules/esm/loader:433:12) at ModuleLoader.loadAndTranslate (node:internal/modules/esm/loader:480:27) at ModuleJob._link (node:internal/modules/esm/module_job:112:19)

Details

May also be related to this warning:
Warning: Module type of file:///Users/raymessina/Desktop/__store%20git/vets-website/src/platform/testing/unit/mocha-setup.js is not specified and it doesn't parse as CommonJS. Reparsing as ES module because module syntax was detected. This incurs a performance overhead. To eliminate this warning, add "type": "module" to /Users/raymessina/Desktop/__store git/vets-website/src/platform/testing/package.json.

Tasks

• Check Mocha configurations
• Check Babel configurations
• What overhead would Webpack entail
• If necessary swap suffixes for .jsx

Acceptance Criteria

• should be able to run test directories with unit tests files with the sufix .js that contain JSX elements.
• other tests and features should not be adversely affected
