Remove extra whitespace from mapping docs

🤨 Rationale

https://nimble.ni.dev/storybook/?path=/docs/components-table-column-mapping--docs

👩‍💻 Implementation

Change to use the table element's name instead of its tag. We use plain text element names and code-formatted element tags pretty interchangeably throughout our docs.

I would mildly prefer to keep using the<Tag> but Prettier is insisting on putting an extra newline before it if it's the first thing on a line. I played with some configuration options and couldn't find one to change that behavior.

Other options include moving this string to the .stories.ts file, adding inline prettier ignores, or debugging further. I went with something simple for a relatively minor bug that I didn't want to spend much time on unless it bothers us in more places, but if this makes you go "ick" I can reconsider.

🧪 Testing

In a local build the whitespace is gone
