customizing goGetDirs leads to renovate artifact failure

How are you running Renovate?

A Mend.io-hosted app

Please tell us more about your question or problem

I have got a repository, which has a go.mod file in the root and in a certain sub-directory, i.e. foo/go.mod.
I would want renovate to only check the foo/go.mod.

Actual behavior of renovate

With

{
  "goGetDirs": ["./foo"]
}

Renovate reports an: ⚠️ Artifact update problem

Command failed: go get -d -t ./foo
go: -d flag is deprecated. -d=true is a no-op
go: ./foo (/tmp/renovate/repos/github/REDACTED/REDACTED/foo/foo) is not a package in module rooted at /tmp/renovate/repos/github/REDACTED/REDACTED/foo

Desired behavior of renovate

With

{
  "goGetDirs": ["./foo"]
# or
  "goGetDirs": ["./foo/"]
# or 
  "goGetDirs": ["./foo/."]
}

renovate should execute:

cd foo
go get -d -t  .
cd ..

Equivalently, with

{
  "goGetDirs": ["./foo/..."]
# or
  "goGetDirs": ["./foo/./..."]
}

renovate should do

cd ./foo
go get -d -t ./...
cd ..
