nomad: Pin to go1.14 for 0.11 and 0.12

This commit pins go versions for nomad 0.11 and 0.12. Future versions of
Nomad should have their versions pinned from the beginning, even if they
support the latest-at-the-time version of Go to prevent accidental
version bumps on unsupported go versions.

See #96414 for further discussion
around this change.
