Consider removing the `variant` property on `Text` in favor of just using Markdown

Currently, Markdown allows you to specify H1, H2, H3 etc through `# Heading 1` etc, but we also redundantly provide a `variant` parameter for this.

How about we remove this redundancy? It's awkward to implement also. What if we have a `h1` variant Text, with `#### Subtitle` in it? Which level is that heading?

Look for the Text component definition, likely in a file like Text.tsx or a components directory. Identify where the variant property is used and how it interacts with Markdown parsing. Check for any tests related to Text or heading rendering to understand the expected behavior. The goal is to remove the variant property while ensuring Markdown headings (#, ##, etc.) are correctly rendered.
