Upgrade Vuepress, Flow, and misc (#1646)

* improvement(vuepress): upgrade VuePress to version 1.x

Upgrade vuepress docs server to 1.x to gain recent features and bugfixes

* improvement(corejs): upgrade core-js to version 3.x

Upgrade core-js to version 3.x to gain new featurs and bugfixes. Version 2.x is no longer
maintained.

* chore(chalk): upgrade Chalk

Upgrade Chalk to latest major release

* build(flow): upgrade flow from 66 to 133

Removed suppress comment option as it is removed from flow 133. $FlowIgnore is now a supported
suppressed comment. See https://flow.org/en/docs/config/options/#toc-suppress-comment-regex for more
details.

* refactor(typescript): pin Typescript to ^3.9.7

* chore(cross-env): upgrade cross-env to v 7.x

Major change includes environment deprecations, which drops support for Node < 10.x
