Pins GitHub actions to Node 16 (#2010)

## Description

- Pins GitHub actions that now default to node 18 to node 16
- sets node engine to 16 in `package.json`

## Motivation and Context
<!--- Why is this change required? What problem does it solve? -->
<!--- If it fixes an open issue, please link to the issue here. -->
<!--- use keywords (eg "closes #144" or "fixes #4323") -->

All of our jest tests the imported files using `data-forge` were failing
to run. Something must break when running on node 18 (the new default)
instead of node 16, so for now this PR pins our yaml files to node 16

actions/runner-images#7002
