Use windows-2019 in release CI (#3090)

## Issue Addressed

NA

## Proposed Changes

Address a CI failure in the release suite.

Example: https://github.com/sigp/lighthouse/actions/runs/1984266187

## Additional Info

I believe we should merge this into `unstable` and `stable`. Then, move the `v2.1.4` commit to target the commit with the updated CI. It's sad that v2.1.4 has two commits, but they're functionally equivalent for users.
