Change names of our bundles

[chriddyp]

Right now, we name all of our bundles bundle.js. We should rename these bundles the name of the JS library to make debugging / inspecting errors in the console easier. That is, across:

• In dash-renderer: bundle.js ➡️ dash_renderer.min.js
• In dash-core-components: bundle.js ➡️ dash_core_components.min.js
• In dash-html-components: bundle.js ➡️ dash_html_components.min.js
• In dash-component-boilerplate: bundle.js ➡️ the_package_name.min.js

These changes can happen in the individual component libraries, e.g. here: https://github.com/plotly/dash-core-components/blob/29d9f1d366b64a2759fbfc74d184a0561288284d/dash_core_components/__init__.py#L42-L47
we shouldn't need to change anything in dash itself. I'm creating this issue in dash just to organize things across the repos 😺

Should I do it in the serve dev bundle PRs while I'm at it ?

@T4rk1n - Yup, that works!
