puku doesn't work with ./pleasew

[manfredlift]

I am installing puku as a please tool as per the readme:

[Alias "puku"]
Cmd = run //third_party/binary:puku --
PositionalLabels = true
Desc = A tool to update BUILD files in Go packages 

When trying to puku sync it complains about not finding plz.

$ ./pleasew puku sync -w
15:21:58 CRITICAL failed to query config: %!w(*errors.errorString=&{exec: "plz": executable file not found in $PATH
})

I believe ./pleasew installs please in ~/.please with the name please so there's no chance for puku to ever find it as plz even if the $PATH gets set correctly?

It kinda works with puku.json, but not in a general way:

{
  "pleasePath": "/User/<my-user>/please",
}

It appears that pleasePath doesn't allow for env var substitution so $HOME/.please/please or ~/.please/please doesn't seem to work.
