Product analytics instrumentation SDK example code is invalid

What does this MR do and why?

Updates the product analytics example SDK instrumentation code to be valid JavaScript: glClientSDK({ 'value', 'value' }) becomes glClientSDK({ appId: 'value', host: 'value' })

Update applicationId to appId inline with the SDK. This only happens when product_analytics_snowplow_support feature flag is enabled.

Also specify package version 0.0.5 when feature flag is disabled so the Jitsu-supported SDK is used.
