Prefer installing version from toolchain directive

Browse source 
Prefer this over the version from the `go` directive. Per the docs[1]

> The toolchain line declares a suggested toolchain to use with the
module or workspace

It seems reasonable to use this, since running this action in a
directory containing a `go.mod` (or `go.work`) suggests the user is
wishing to work _with the module or workspace_.
