'spfx doctor' should support also gulp-cli v3

[Adam-it]

So it seems currently in spfx doctor we validate if gulp-cli is either v1 or v2

if we check the spfx docs we will see the guide will actually install the latest gulp-cli which is v3

From what I checked SPFx should work properly with gulp-cli@3 and I got it confirmed from Alex as well.

Lets add this support

@Adam-it, did you also learn starting from which version SPFx supports gulp-cli@3?

@Adam-it, did you also learn starting from which version SPFx supports gulp-cli@3?

From when it was released. So 3 months ago so the first version is 1.18 no sooner

I suggest that we don't make assumptions and instead check with Alex

[Adam-it]

sure thing. I pinged Alex. Will keep you updated 👍

@waldekmastykarz after rediscussing this topic with Alex and rechecking it myself we agreed it's best to add gulp-cli@3 only for SPFx 1.19.0 and later versions.

Thank you for confirming @Adam-it
