chore: improve documentation for localhost links and useCoreSdk examples

[Copilot]

Description

Enhanced documentation clarity and usability:

• Localhost URLs: Converted plain text URLs to clickable markdown links in docs/boson-environments.md for local environment configuration table (subgraph, dApps, and widgets)
• React hook examples: Updated useCoreSdk code examples in docs/guides/use-with-react.md to include proper import statement and required configId parameter
• Code formatting: Applied consistent line breaks in packages/common/src/configs.ts for IPFS gateway URLs

// Before
const readOnlyCoreSdk = useCoreSdk({
  envName: "testing"
});

// After
import { hooks } from "@bosonprotocol/react-kit";

const readOnlyCoreSdk = hooks.useCoreSdk({
  envName: "testing",
  configId: "testing-80002-0"
});

How to test

• Verify markdown links render correctly in docs/boson-environments.md
• Confirm useCoreSdk examples in docs/guides/use-with-react.md are copy-paste ready with valid imports and parameters
