chore: override d3-color to ^3.1.0 and fix issues introduced in previous depbot PRs

[jdstrand]

This updates d3-color for transitive dependencies to also use 3.1.0, fixing an unimportant dependabot alert. Instead of dismissing the alert, move forward so we can continue to maintain this repo. This required a change to giraffe/jest.config.js due to a change in d3-color 3.1.0

In testing this, it was discovered the PR #886 broke CI since it needed node >=18, but we only had 16 (for some reason, build wasn't required to pass and was missed). In working through that, it was discovered that node-sass is unsupported and needs node 18 or earlier, which is EOL. As we move forward with dependabot updates, dependencies will require node 20 or newer more and more, so use the supported sass and update to cimg/node:24.20 (current lts; we don't use lts yet since it will move to 26 at some point, potentially breaking builds).

webpack v4 uses MD4 which is removed from openssl 3. Newer versions of node (after 14) use openssl 3, so pass NODE_OPTIONS=--openssl-legacy-provider to storybook (which calls webpack) until we can upgrade.

Run yarn run build-storybook in CI.

I updated the giraffe circleci setting to require build to pass. Hopefully that will help going forward.

@eatondustin1 - hey, can you re-review? I had to make a number of additional changes after realizing the repo wasn't passing build for a while. Thanks!
