Check node version for CRA in Initialization component

[AWolf81]

Describe the bug Project creation fails with-out an error message because of an old node version (see screenshot below). I have to update my VM ware node version.

To Reproduce

1. Check your node version and use a version <8.10.0 (e.g. 8.9.3) (use nvm)
2. Enable LOGGING in src/config/app.js
3. Create a new CRA project
4. Check the console output

Expected behavior

• On app load check that the Node version is matching the required version. If not, display a message and don't render guppy.
• Or we could add a check to Project creation for CRA to catch the error, display a message & abort installation.
• Version to check see screenshot. Check with semver & check three versions 6 || 8 || 10.

TODOs

• [ ] Check requirements of Gatsby & Next.js. We have to meet these version too.

Screenshots

Environment (please complete the following information):

• OS: Ubutnu 16.04.3 (but will also occur cross-platform)
• Version: master
• Node version: 8.9.3

Hi @AWolf81

Happy to look into this. Thinking it might be a good place to use the info bar created in #352 to display the error. What do you think?

On app load check that the Node version is matching the required version. If not, display a message and don't render guppy.

I can't seem to see a clear node version that's required to run Guppy, if it can be run on any version then showing the app isn't wrong? What do you think?

@joshuaellis Please have a look into it.

Yes, I think the info bar works here too.

We can render everything and just show the info and disable project creation if the Node version is not correct.
