Add Migration Guides for PnP Modal and No Modal SDKs (v9 to v10)

[ihsraham]

Motivation and Context

This change adds complete migration documentation for upgrading Web3Auth PnP Modal and No Modal SDKs from v9 to v10.
It addresses the architectural changes introduced in v10, such as the removal of verifiers and adapters from frontend code, and the introduction of connectors, authConnectionId, and groupedAuthConnectionId.

It also simplifies frontend usage across React and non-React stacks and clarifies changes to private key providers, dashboard-based chain config, and wagmi-based blockchain calls.

Description

• Added two new MDX documentation files:

  • modal-v9-to-v10.mdx
  • no-modal-v9-to-v10.mdx

• Both guides cover:

  • Breaking changes from v9 to v10
  • Changes in social login configuration (verifier to authConnectionId)
  • Adapter removal and use of connectors
  • Chain config and private key provider migration to dashboard
  • Updated usage for React (hooks) and non-React examples
  • Wagmi integration in no-modal and React

• A side-by-side comparison table summarizes migration changes

• No runtime code changes included

---

How has this been tested?

• Rendered the MDX files locally in the Docusaurus environment
• Verified markdown structure, code block formatting, and table alignment
• Manually confirmed all contextual descriptions, especially for breaking changes
• Cross-compared against v9 and v10 example apps to ensure accuracy

Screenshots (if appropriate)

N/A — content-only change
