Add authentication endpoint

[johnwatkins0]

Is your enhancement related to a problem? Please describe.

A HeadstartWP-based project I'm working on requires a way to authenticate WordPress users within the Next.js app. While an additional third-party plugin such as JWT Authentication for WP REST API can be added for this purpose, the Headstart WP plugin already has a class for generating JWT tokens, so I propose adding an authentication REST endpoint within the plugin.

The endpoint would need to support different expiration times for the token (configurable perhaps via a filter), and the data returned from the REST endpoint should be filterable to provide any other user-specific data needed in the Next.js application such as roles, etc.

For the Next.js side of things, it may be sufficient for this repo to provide documentation for the integration.

It's also an option to use a third-party plugin to provide an authentication endpoint.
