Version 2.8.0

Update a number of dependencies.

New version `2.6.0`

This version contains updates to various dependencies in the project.
The only outstanding dependency update is `flow-bin` which is proving to
be quite a challenge given that we can no longer import `Action`,
`Dispatch`, or `Store` from Redux. This will be tackled in a later
version.

Update to version `2.5.0`

This update includes a variety of dependency updates and the removal of
the Publish workflow.

Update package version

This commit bumps the redux-action-analytics-middleware package to
version `2.4.0`.

Create npm-publish.yml

This commit introduces a new workflow that will publish the updated
package to NPM once there is a new release created in GitHub.
