deps: update go-plugin to 1.6.2 (#24265)

Browse Source 
During allocation recovery, the go-plugin reattachment workflow checks to see if
the PID we stored in client state is still running. If so, we try to connect to
that process. If that fails, we kill the process under the presumption it's not
working. But during reattachment we don't know that the PID we have is still
valid. Which means that the process we're trying to attach to may have exited
and a different process has spawned with the same PID. This results in some
unrelated process getting silently killed.

Update go-plugin to 1.6.2, which includes a bug fix so we do not kill the
process.
