Fix website...again

Summary:
Still getting dependabot PRs.  I ran `yarn audit` and got this:

```
$ yarn audit --summary
yarn audit v1.22.21
⠁ (node:1917004) [DEP0169] DeprecationWarning: `url.parse()` behavior is not standardized and prone to errors that have security implications. Use the WHATWG URL API instead. CVEs are not issued for `url.parse()` vulnerabilities.
(Use `node-linux-x64 --trace-deprecation ...` to show where the warning was created)
328 vulnerabilities found - Packages audited: 1948
Severity: 5 Low | 132 Moderate | 110 High | 81 Critical
Done in 2.58s.
```

I then ran `yarn upgrade`, `yarn install`, and `yarn build`.  After fixing a webpack pinning issue, the website now builds and there are a bunch of updated dependencies.

Note that `yarn audit` still isn't totally clean, but there are many fewer.  I think the remaining issues are due to pinned packages, we probably need to go through and winnow down our packages.json file to minimize the number of pinned packages.
