Update GitHub Issue Template CodeSandbox

[BrendanC23]

Currently, the RHF GitHub issue template lists a CodeSandbox for a TypeScript project and for a JavaScript project.

• JS
• TS

These CodeSandbox projects are outdated. For example, here are some of the dependencies from package.json:

{
  "dependencies": {
    "@hookform/devtools": "2.0.0-beta.3",
    "react": "^16.12.0",
    "react-dom": "^16.12.0",
    "react-hook-form": "7.4.1",
    "react-scripts": "4.0.1"
  },
  "devDependencies": {
    "@types/react": "16.9.19",
    "@types/react-dom": "16.9.5",
    "typescript": "3.7.5"
  }
}

Can these templates be updated to use the latest packages?
