Update the NPM dependencies

[ahukkanen]

When you run a clean npm install at the server app or the JS packages contained in this repo, we get the following deprecation messages:

npm WARN deprecated urix@0.1.0: Please see https://github.com/lydell/urix#deprecated
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated resolve-url@0.2.1: https://github.com/lydell/resolve-url#deprecated
npm WARN deprecated chokidar@2.1.8: Chokidar 2 will break on node v14+. Upgrade to chokidar 3 with 15x less dependencies.
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

To replicate this, do the following:

• Go to the server app cd bulletin_board/server
• Remove the node_modules folder if it already exists rm -rf node_modules
• Install the NPM packages npm i

Also, we get NPM audit issues that should be fixed:

25 vulnerabilities (7 moderate, 16 high, 2 critical)

These should be fixed as well.

So, let's update the NPM dependencies in all packages that contain NPM dependencies:

• bulletin_board/server
• bulletin_board/js-client
• voting_schemes/dummy/js-adapter
• voting_schemes/electionguard/js-adapter
• verifier
• voting_schemes/electionguard/verifier
