Update nuxt prerequisites on doc site

[agnelnieves]

Hey guys, I just had an issue where wasn't able to properly create a nuxt project.

I opened an issue on this. Turns out my problem was that I was using node v11, and is not supported. However, on the docsite, says node - at least v10.13 which might be a bit confusing for other people in the future.

So thought there might be value in updating this sentence to exclude v11

Props to @danielroe for helping me out

Sure. Pr welcome 😊

Thanks @agnelnieves 😃 Note that you should have been warned - I'm fixing the issue in nuxt/nuxt#8841.

For the docs, I recommend similar wording to the warning in CLI:

It is recommended to use the latest LTS version of Node.js - currently v12.

Awesome, thanks @danielroe & @debs-obrien, might do a PR later. If anything, assign this issue to me
