Use GitHub Action to cut new releases

[agarzola]

Description

Currently, releases are the product of running yarn version --[major|minor|patch] locally, then pushing up the resulting commit and tag, and running npm publish. This should be something we handle with a GitHub Action that anyone on the team can run on-demand.

Proposed Solution

Find a GH Action in the marketplace that can create and publish new releases to npmjs.com. Ideally one that also adds information about what went into a release.

Alternatives Considered

None.
