WIP - January 2025 npm updates

[stevector]

This PR updates npm dependencies and removes a bunch of unused variables (clean up that will be mildly helpful when we eventually port this site out of Gatsby)

@jazzsequence @rachelwhitton here's an interesting thing, this workflow failed because it the diff included deleted files (and prettier can't run against a deleted file). So this filter displays only added or modified files.

Deploy is failing which makes me think that the build is failing.

Looks like the same build error here as PR 9394 - strange since this PR doesn't update the pantheon-systems/pds-toolkit-react package

Gus has since fixed this build error over in PR #9394 fyi @stevector
