Fix broken reference links in lerpColor() documentation (p5.js 2.0)

[rakesh2OO5]

Summary

Fixes broken reference links in the lerpColor() documentation for p5.js 2.0.

The links to lerp and colorMode were pointing to incorrect hash targets, which resulted in 404 errors on the current reference site.

What Changed

Updated JSDoc links in src/color/creating_reading.js to use the existing hash-based reference format used elsewhere in the docs:

• #/lerp → #/p5/lerp
• #/colorMode → #/p5/colorMode

Verification

• Reproduced the 404 issue on the beta reference site.
• Ran npm run docs locally.
• Confirmed the updated links appear correctly in docs/reference/data.json and point to valid reference pages.

Scope

Docs-only change (JSDoc). No runtime or API behavior affected.

Fixes Issue #8506
