Clean up package.json files in the `examples` directory:
- Add `private: true`
- Remove `version` (because they are irrelevant for packages that are not meant to be published)
- Remove `name` (because they are optional for packages that are not meant to be published, and when someone clones an example, they often rename it and the property becomes stale)
- Remove `author`
- Remove `description`
- Remove `license`
Also remove `with-dynamic-app-layout` example completely, since it does the same as `layout-component` (https://github.com/vercel/next.js/pull/27121#discussion_r668178408).
## Documentation / Examples
- [x] Make sure the linting passes
[With next 11 requiring react 17](https://nextjs.org/blog/next-11#upgrade-guide), most of the examples
need to be updated, so the following snippet updated all the examples to
a compatible react version.
```bash
cd examples/
fd -g 'package.json' | xargs sed -r -i 's/"react": ".*"/"react": "^17.0.2"/
fd -g 'package.json' | xargs sed -r -i 's/"react-dom": ".*"/"react-dom": "^17.0.2"/'
# exclude experimental react version
git checkout with-reason-relay/package.json
```
This PR adds a `Preview` section and a `Open in StackBlitz` button to various examples. I have tested all examples and omitted the ones that require third party API keys, or didn't work. Some examples don't work locally either.
Here's an example:
## Bug

remove `alwaysStrict: true` rule from tsconfig.json in with-typescript example, because the rule is included in `strict: true` has been already written in tsconfig.json and other included rules such as `noImplicitAny: true` have not been written.

Get rid of the unmet peer dependency warning when installing
a next.js project wtih node-sass 5.
node-sass 5 is the currently maintained version and removes
support one deprecated API and Node.js versions that Next.js does
not support either. Next.js uses node-sass 5 in devDependencies.
node-sass changelog: https://github.com/sass/node-sass/releases
On the other hand, as the docs encourage the sass package instead of node-sass,
(see errors/duplicate-sass.md)
I have updated examples which used node-sass 4 to the latest sass instead.
