dbt: add adapter to dbt docs's "Available Adapters" page

[dataders]

The Available Adapters page is one of the dbt community's most-visited docs pages. It would be of great benefit for first-time visitors to the dbt docs to see:

1. that this adapter is a possible option for using dbt-core, and
2. how many large the dbt ecosystem of support databases is.

dbt-labs/docs.getdbt.com#1489 exists to address this with all as-of-yet undocumented adapters.

We just released Documenting a new adapter, a new guide on how to add an adapter to the Available Adapters page. I'd love to see this adapter on that page, so feel free to reach out with any questions/blockers by either replying to this issue, or posting in the #adapter-ecosystem channel of the dbt Community Slack.

Looking forward to the contribution!
