Stop wasting time on versioned docs

[jhaven-stytch]

Changes:

1. Stop trying to generate versioned docs since we only expose latest version docs

Notes:

• Since the introduction of the UI SDK, we've stopped supporting versioned docs, as Dokka multi module + versioning doesn't seem to be supported. We decided to just live with latest-version docs, but never updated the workflow. This was fine, but costly, as we were running doc generation for versions that were never going to be exposed. However, v0.25.0 introduced some changes that broke dokka generation (and have since been fixed), but that meant that attempting to generate versioned docs failed for that version and, thus, failed to generate any docs. So, this codifies that we are only doing latest version docs, gets our doc publishing working again, and maybe saves a little money on runners.
