Drop Node.js required version from 8.15.0 to 8.7.0

Via #4000 (comment)

As AWS Labda currenty only supports Node.js 8.10, let's drop the required version down to 8.0.0

We can add this to the next minor release 10.0.1

What if we, or our dependency, uses a feature introduced in 8.3.0 for example?

What if we, or our dependency, uses a feature introduced in 8.3.0 for example?

I tested locally with 8.0.0 and stylelint crashes out with

/Users/jeddy3/Projects/stylelint/node_modules/micromatch/index.js:44
    let isMatch = picomatch(String(patterns[i]), { ...options, onResult }, true);
                                                   ^^^
SyntaxError: Unexpected token ...

This is because micromatch uses the object spread operator which is behind a flag until 8.3.0.

micromatch has >=8 in its package.json, which gives me the impression that this engine field is a bit problematic.

According to node.green the following versions added new features:

• 8.7.0
• 8.3.0

Even though stylelint works with 8.3.0 I suggest we go with 8.7.0 as that's the lowest feature-complete version of 8 (and it's compatible with AWS). This seems to me to be the best compromise.

Thanks, makes sense, have bumped it to 8.7.0

LGTM.

@hudochenkov Did you have any more thoughts on this? I can put out a patch release this morning if this goes in.

[hudochenkov]

LGTM!
