Don't look for for non-top frame locals in node >=18 during locals tests

Important

Post-merge comment

Locals seem to be available after all but changes in how Node 18 deliver call frames has broken our mechanism to extract these.

This is now a bug, and we should be able to revert these changes once we figure out how to extract locals for Node 18+.

Refer to ticket SC-134017.

Description of the change

This PR fixes a failing test running over false assumptions around node/v8 locals in stack traces.

After careful testing, beginning Node.js 18, it seems locals are only present in top frames. However, I wasn't able to pinpoint documentation about this.

Note

This PR also updates CI to run installs and tests under lts nodes 14 through latest.
