Fixes: #38232
Fixes: https://github.com/vercel/next.js/issues/36893
Version [12.1.1-canary.5](https://github.com/vercel/next.js/releases/tag/v12.1.1-canary.5) introduced a bug, more specifically this PR: https://github.com/vercel/next.js/pull/34836
The issue described in #38232 is that the following code starts both the dev and prod servers:
```js
const start = require('next/dist/cli/next-start')
start.nextStart()
```
I searched a bit and found that `lib/get-project-dir.ts#getProjectDir()` now imports `bin/next.ts`
6b8e499c7b/packages/next/lib/get-project-dir.ts (L3)
and it calls a CLI command via
6b8e499c7b/packages/next/bin/next.ts (L137)
This `command` should not be defined, but it fallbacks to `defaultCommand`, which is `dev` (that explains why the dev server is also started)
This PR moves the `cliCommand` types and `commands` variable to a new separate file instead of `bin/next.ts`, to avoid running a CLI command when we import any file that also imports `lib/get-project-dir.ts`
Not sure how integration tests can be added for this issue, but feel free to tell me.

Makes it easier to detect why a network error occurred with the CLI or `next info`, based on https://github.com/vercel/next.js/issues/36344

I noticed a few issues that had "Output from `next info`" with the first line as
```
/bin/sh: pnpm: command not found
```
This was because `execSync()` was still printing to stderr when a command was not found.
Changing to `execFileSync()` fixed it so we no longer print to stderr when a command is not found.

When opening a new issue, it is desired that the user has checked if the `canary` release not already have fixed their issue, since we do not backport fixes to previous Next.js versions.
- added a CLI warning when `next info` runs that looks like this:
This links to a message docs page with more information and some useful links.
- refactored our bug report templates to be more clear and removed the fields that are now unnecessary (since running `next info` is expected to run on releases that already have it)
- Made browser/deployment optional, as in most cases those fields are irrelevant. We still ask them, but mention that they are only needed if relevant.
- Asking for the exact browser version now

This PR adds a new command to the `next` CLI.
Running `next info` will print useful information to the terminal about how/where Next.js is run. This information can be added to the Bug report when opening an issue in the repository.
This makes reporting issues more accurate and doesn't require the user to guess certain details, the command will retrieve it on their behalf.
Example output:
```sh
$ npx --no-install next info
Operating System:
Platform: linux
Version: #22-Ubuntu SMP Fri Nov 5 13:21:36 UTC 2021
Binaries:
Node: 16.13.0
npm: 8.1.0
Yarn: 1.22.17
pnpm: 6.24.2
Relevant packages:
next: 12.0.8-canary.14
react: 17.0.2
react-dom: 17.0.2
```
The idea is based on #32858
