Specify not only the major version of the dependencies listed in the package.json generated by create-next-app, but also includes the patch version

[shuta13]

Goals

1. Specify all dependencies listed in package.json generated by create-next-app, including minor versions.

Non-Goals

No response

Background

Errors when installing a package with @types/react etc. as peerDependencies in a project generated by create-next-app.

Fix the upstream dependency conflict, or retry
this command with --force or --legacy-peer-deps
to accept an incorrect (and potentially broken) dependency resolution.

It is more user-friendly to specify even minor versions.

Proposal

Modify implementations in the shown below part.

next.js/packages/create-next-app/templates/index.ts

Lines 173 to 223 in a6215cc

Rewrite the part that specifies only the major version to include the minor version. I will create PR if necessary :)
