Log cached WooCommerce version along track events

[iamgabrielma]

Description

We have found ourselves a few times in iOS with lack of data when trying to check WooCommerce versions from the track events dashboard, for example, recently when deciding if would be good enough to increase the threshold of a feature from 9.6 to 9.7, since we could only rely on Android data and guess iOS user base distribution would be similar

This PR mimics Android's approach to pass the WooCommerce version as default property along track events.

For this we retrieve, store in memory, and pass the woo version through the cached_woo_core_version property (for consistency with Android naming) to all track events, following the same pattern as others like isWpcomStore.

Test Steps

• With 2 different woocommerce stores, on different woocommerce versions (or test with the same store by updating the version)
• Run the app, note in the console how cached_woo_core_version tracks the woo version
• In menu > change store, note the version tracked is correct.

Store 1:

🔵 Tracked ... cached_woo_core_version: 10.3.6 ... blog_id: 250994203]

Store 2:

🔵 Tracked ... cached_woo_core_version: 10.4.2 ... blog_id: 215063064]

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

Looks good and helpful, thanks for adding it.

FYI I struggled to test the caching – changing woo versions caused lots of other problems on my test sites and I'm a bit short of time to go deep on it. If you've seen it working, I'm sure it's fine, and the risk is low anyway.
