amend kubetrim to access compressed binaries

[rgee0]

Description

Kubetrim has been amended to provide binaries in a compressed form in much the same way as inlets.

This change adjusts the kubetrim template to access the .tgz versions.

Motivation and Context

Kubetrim has been amended to provide binaries in a compressed form in much the same way as inlets.

• I have raised an issue to propose this change, which has been given a label of design/approved by a maintainer (required)

How Has This Been Tested?

make e2e and test-tool will fail until the merge on the kubetrim side produces appropriate binaries

If updating or adding a new CLI to arkade get, run:

go build && ./hack/test-tool.sh TOOL_NAME
