Update frontend dependencies

[jsandoval81]

Requirements List

• yarn install --ignore-engines

Description List

• Updated cross-spawn
  • https://github.com/csg-org/CompactConnect/security/dependabot/56
  • cross-spawn@7.x & cross-spawn@6.x were able to be updated normally
  • cross-spawn@5.x required a new resolution + confirmation that the update to 6.x for that case was not breaking
    • In addition to smoke testing, looking at the release notes for the parent dependency execa as it moved cross-spawn from v5 to v6 as part of the execa@1.0.0 release, the code & notes for the release suggest it was just a version bump to mark the release as stable and that there were no breaking changes.

Testing List

• yarn test:unit:all should run without errors or warnings
• yarn serve should run without errors or warnings
• yarn build should run without errors or warnings
• Code review

Closes #340

Heads up that this is also in the cloudfront-csp lambda and owasp-zap authenticator lambda. Not sure if thats a seperate ticket / instance of addressing

Edit: I guess thats just in es-lint so not the built lambdas

@ChiefStief It looks like yesterday dependabot withdrew the original alert and issued a revised alert. The revised alert bumped down the major version requirement to v6. This made it so that the v5 dependency for @vue/cli-plugin-eslint could be resolutioned to v6 without breaking.

I've made the corresponding updates and also updated the PR and ticket notes.
