CircleCI publishes outdated `plot-schema.json`

[antoinerg]

On CircleCI publish happens right after the build job.

The build job on the CI is npm run cibuild which doesn't update the plot-schema.json. We should update it either by:

1. adding code to https://github.com/plotly/plotly.js/blob/master/tasks/cibundle.js
2. creating a new task only for that purpose which would only be executed in the publish job.

Option 1 adds 15 seconds to the build step. So I would favor option 2 since it can be runned in parallel.

Poor's man benchmark

Option 1

Voting for just calling

plotly.js/tasks/bundle.js

Lines 64 to 74 in fdcdd22

	// Browserify plotly.js with meta and output plot-schema JSON
	tasks.push(function(cb) {
	_bundle(constants.pathToPlotlyIndex, constants.pathToPlotlyDistWithMeta, {
	standalone: 'Plotly',
	debug: DEV,
	noCompress: true
	}, function() {
	makeSchema(constants.pathToPlotlyDistWithMeta, constants.pathToSchema)();
	cb();
	});
	});

in the publish step.

Sounds like a very good idea! I will remove the PR #3160 I just made! Actually, PR #3160 does exactly that!
