Subject: [PATCH] docs: fix undefined `relayClient` in dynamic chain fallback

Fix the fallback in `references/relay-kit/sdk/installation.mdx` by using the imported `mainnet` chain instead of the undefined `relayClient`.

The `catch` block referenced `relayClient.chains`, but `relayClient` is not declared or imported in the example. If dynamic chain configuration fails, this would cause a `ReferenceError` and prevent the fallback from creating the Wagmi config.

Using `[mainnet]` provides a valid fallback chain that is already imported in the example.
