Resolve or Replace @ts-ignore

[justjish]

Description

1. Reordered error checking for SdkProvider so that it will actually throw error for no sdk provided.
2. Resolve @ts-ignore in SdkProvider: v9 exposes props.sdk.app.name for all SDKs, so used that for app name comparison.
3. For the remaining ts-ignores, replaced with @ts-expect-error.

Thanks for this cleanup @sujishpatel! Can you please run yarn docs from the root of the project to make that last check go green?

(Sorry that wasn't clear. I've updated the contributing guide to make it easier for future contributors).
