BB2-4736: Update axios, remove package-lock.json

[JamesDemeryNava]

JIRA Ticket:
BB2-4736

What Does This PR Do?

Updates axios to 1.15.0, removes package-lock.json to reduce confusion over whether or not a dependency has been updated. This project uses yarn, so package-lock.json is no longer needed.

What Should Reviewers Watch For?

• Any concern about removing package-lock.json?

If you're reviewing this PR, please check for these things in particular:

Validation

• Pull down the branch, navigate to client directory and run yarn install
• run yarn list axios (make sure 1.15.0 is shown)
• Run yarn build, make sure it completes successfully (there will be some warnings)
  • Can also navigate to the project root, run docker-compose up -d, load localhost:3000, and go through an auth flow to make sure everything looks good
