[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
```
If the example is cloned and ran with no further setup (no environment variables set up), it will error out because `extractPostEntries` will return `undefined` which can not be serialized by `getStaticProps `.
This PR basically ensures that we return an empty array instead of the `undefined` for a collection of posts, and a `null` instead of the `undefined` for a single post.
Now that all Contentful spaces support GraphQL, we are looking into switching the example from using a JS library to a simple fetch with GraphQL.

Hey guys, thanks for the amazing job you are doing 💜
This PR fixes a small error I faced when starting a project with Prismic + Next.js.
Since the version on the `cms-prismic` example was fixed to `9.2.3-canary.26` I was having the following error because the example uses the environment variables feature that is for Next.js 9.4+
<img width="1256" alt="Screen Shot 2020-06-16 at 12 13 38" src="https://user-images.githubusercontent.com/26466516/84793626-bc43c000-afcb-11ea-8823-b1dee30dbb00.png">
After updating to the latest version, I could run it successfully.
ps: I also realized that the `cms-contentful` example was also not using the `latest` version, so I decided to update it (I have not tested, but the error certainly will happen).
ps2: if you want to reproduce the error, just create a project using the example and add dummy data on the environment variables, then start the server and access `http://localhost:3000`.

- Added new import flow to every CMS example, using the deploy button, and removed `vercel.json`
- Replaced `dotenv` with the new env support in outdated examples

Some README files in `examples/cms-*` were linking to a documentation markdown file inside the repo (e.g. `/docs/basic-features/pages.md`) instead of the documentation website. We should always link to the documentation website from an example README file because (1) the website has better UX and (2) as we’re creating the examples pages on `next-site` (https://github.com/vercel/next-site/pull/672), we’d like to avoid extra processing of markdown content.

The example app expects all fields of Post and Author entries to be present and fails to build if any are missing. This PR adds a "required" validation to fields of both content types to avoid bulid errors.
