[ui] Add Teradata icon for kind tags (#26782)

## Summary & Motivation

Add Teradata Icon (SVG, 20x20) for Asset Kinds.

As part of ingesting data sources for dbt, I frequently pull tables from
Teradara into data lake. Having fancy Teradata icon would improve
clarity and enhance the UI experience.

## How I Tested These Changes

Launched the documentation website locally and verified that the kind
was visible in the Supported Icons section (as in the screenshot below).
