StateStore transactions is not displayed using Go

[salaboy]

What content needs to be created or modified?

In the following section: https://docs.dapr.io/developing-applications/building-blocks/state-management/howto-get-save-state/#perform-state-transactions "Go" examples are not shown.
I found some examples by looking into the Go SDK: https://github.com/dapr/go-sdk/blob/5ef7aa2234d4d4c07769ad31cde223ef11c4e33e/Readme.md?plain=1#L157

This should be displayed in the Docs.

Describe the solution you'd like
Having all the supported languages SDKs displayed in the examples for state trasactions

Where should the new material be placed?
