TypeScript and package.json type module (ESM) shows "ExperimentalWarning: --experimental-loader"

[MikeMcC399]

Current behavior

If package.json is configured with Node.js type field set to module (instead of left undefined or set to commonjs), Typescript is installed and config.cypress.ts is present, then the following warning is output when running Cypress:

(node:3666) ExperimentalWarning: --experimental-loader may be removed in the future; instead use register():
--import 'data:text/javascript,import { register } from "node:module"; import { pathToFileURL } from "node:url"; register("file%3A///home/mike/.cache/Cypress/13.15.0/Cypress/resources/app/node_modules/ts-node/esm/transpile-only.mjs", pathToFileURL("./"));'
(Use node --trace-warnings ... to show where the warning was created)

Desired behavior

Cypress should not show any warning when set up as a TypeScript project and package.json includes "type": "module" for an ESM project.

(node:3666) ExperimentalWarning: `--experimental-loader` may be removed in the future; instead use `register()`:
--import 'data:text/javascript,import { register } from "node:module"; import { pathToFileURL } from "node:url"; register("file%3A///home/mike/.cache/Cypress/13.15.0/Cypress/resources/app/node_modules/ts-node/esm/transpile-only.mjs", pathToFileURL("./"));'
