Many providers depend on gotestfmt in custom tests

[iwahbe]

Many providers invoke gotestfmt in preTest provider test blocks. They relied on gotestfmt being installed. Since #1069 uninstalled gotestfmt, the workflow upgrades are now failing CI.

Example of a provider using gotestfmt in .ci-mgmt.yaml:

actions:
  preTest:
    - name: make upstream
      run: |
        make upstream
    - name: Run provider tests
      run: |
        cd provider && go test -v -json -count=1 -cover -timeout 2h -tags=${{ matrix.language }} -parallel 4 . 2>&1 | tee /tmp/gotest.log | gotestfmt

(src)

It looks like this effects about 40 providers. You can see a list of failing workflow upgrades here.
