chore(deps): refresh react-next16-ts dependencies

[MikeMcC399]

Situation

Vercel has reported a critical vulnerability CVE-2025-55182 in next<16.0.7.

Change

Convert next, react & react-dom npm dependencies to semver caret range format (^) to allow simpler version maintenance, then use npm update --save to update dependencies.

This includes updating from [email protected] to [email protected].

Verification

Execute:

cd react-next16-ts
npm ci
npm audit
npm run cypress:run

and confirm "found 0 vulnerabilities" and "All specs passed!".

Consider also changing settings under https://github.com/cypress-io/cypress-component-testing-apps/settings/actions to

Require approval for first-time contributors
Only users who have never had a commit or pull request merged into this repository will require approval to run workflows.

It looks like at the moment the setting is more restrictive (although I can't view it myself, I'm just judging by the fact that my PR is waiting for approval to run a workflow, and I have already contributed to this repo):

Require approval for all external contributors
All users that are not a member or owner of this repository will require approval to run workflows.

@AtofStryker

This PR would also need review and merge, if you care to take a look!

@MikeMcC399 I'll merge this in shortly. Thank you for bringing the CVE to my attention. There are a few other repos I need to update!
