feat(cli): render build-docs with Redoc CE 3

[ivankropyvnytskyi]

What/Why/How?

Replaces Redoc 2 with Redoc 3 in the build-docs command.

• New options: --openapi (replaces the deprecated --theme.openapi), --inlineBundle (embed the scripts instead of loading them from the CDN), --disableTelemetry (off by default).
• Supports AsyncAPI descriptions and GraphQL schemas next to OpenAPI 3.0/3.1/3.2.

Not finished yet: After Redoc 3 is released: set the exact version in packages/cli/package.json, regenerate the e2e snapshots and the smoke page, and verify the CDN mode.
