fix: avoid injecting a layout wrapper

[ayaanoncrypto]

Summary

Fixes #2164.

Remove the extra div injected by RainbowKitProvider when a theme is active. The provider now uses a fragment, so application children keep their original DOM structure and layout behavior. Theme CSS injection remains unchanged.

Validation

• git diff --check passed.
• • The repository dependency tree did not include local Prettier or TypeScript binaries, so those checks were unavailable in the sandbox.

Keep a data-rk ancestor for inline components

With the default non-null theme, replacing this element with a fragment removes the only data-rk ancestor from ordinary provider children. The build prefixes all Vanilla Extract selectors with [data-rk], and components such as ConnectButton do not call useThemeRootProps, so a normally rendered connect button no longer matches its CSS rules or inherits the theme variables; only portal dialogs explicitly add the attribute themselves. Retain a non-layout theme root or attach the theme-root props to every inline RainbowKit component root.

Add a changeset for the provider behavior change

This changes the default provider's rendered DOM and is explicitly a user-facing bug fix, but the commit contains no .changeset entry for @rainbow-me/rainbowkit. Without one, the release queue will not version or document this package change, so it can be omitted from the next release unless an unrelated changeset happens to include the package.
