Clean and update packages

[jattiman]

Describe your changes

• Deletes yarn.lock in favor of preexisting package-lock.json
  • Since npm is the package manager referred to in the project documentation (yarn is not mentioned), I believe this is the best route to take.
• Updates packages to address security vulns.
  • Ran npm update to do this. Only 3 moderate vulns should exist now.
  • npm run dev successfully runs project locally after the update.

Note for testers

• the npm run build command doesn't currently work

  • Error output relates to the lack of a csv file's presence

    NotFound [Error]: Not found: /knowledge-hub/ClimateTown-Knowledge-Hub-resources.csv

  • This same error would also produce itself with a yarn build command on the current main branch. I think it's a separate issue from this PR, but wanted testers to be made aware.

• I can't get the dev container to work (hence why I'm running the project locally). I also think this is a separate issue from this PR, but wanted testers to be aware.

Related issue number/link

No open issues are resolved with this PR. It's more of a package refactoring to help ensure that the same build process is followed moving forward.

Thanks for the PR @jattiman !

• the npm run build command doesn't currently work

This command should only be run in CI as it's to create the production build. For development run npm run dev (mentioned in readme :) )

Hmm, weird the codespaces isn't working. I'll make an issue
