Investigate replacements for Node.js 18 LTS

[colin-welch]

Description
Node.js 18 LTS is end-of-life in April 2025. We've had users try newer Node.js versions and run into problems.

Design
Test out newer Node.js versions and fix any issues with them. Validate that compatible versions work automatically going forward.

After picking a new minimum version, we will need to decide on messaging since it is a breaking change of sorts.

Acceptance criteria

Note for QA team

Automated tests will run on new version of Node.js. Local environments will need to be updated to match new verison(s).
