Track and display introduction version for Deno Runtime APIs

Add per-API version metadata and surface it in the docs as small chips. Examples how this could look like:

- "Added in vX.Y"

- "Stable since vX.Y"

- Deprecated in vX.Y

etc (basically something similar to what node already does).

P.S. I searched the issue tracker but couldn’t find an existing issue for this. apologies if I missed it and this is a duplicate

Start by locating how the Deno Runtime API Reference is generated and where API metadata is defined. Determine how per-API introduction, stability, and deprecation versions should be represented, then render chips such as “Added in vX.Y” in the docs. Done means the relevant API pages display accurate version metadata consistently.
