[RN] Updated Universal Developer Image - update to golang language server `gopls` 0.10.1

= Updated Universal Developer Image In {prod-short} {prod-ver}, the Universal Developer Image (UDI) is updated as follows: * `gopls`, link: https://github.com/golang/tools/tree/master/gopls [the Go language server], is upgraded to version 0.10.1. [TIP] ==== To include other tools or runtimes, an administrator can extend, fork, or replace the UDI image with one that includes the tools appropriate for your organization and your users' needs. That replacement image can then be referenced in the `CheCluster` custom resource, so that users can use the custom image in their devfiles. This will ensure that the tools and runtimes they need are persistent and do not need to be installed on each workspace startup. Users can also develop their own UDI image(s) and refer to them from their devfiles, as long as the image is published to a registry that is accessible from their organization's cluster. However, this approach is less centralized and standardized, and may not scale or perform as well. ====
