Update packages

[TyHil]

Based on UTDNebula/utd-clubs#698 and UTDNebula/utd-clubs#704

Changes

• update to Typescript 6
  • remove deprecated stuff from tsconfig.json
• update most packages to their latest versions
• add type:check npm script
• update lint-check GitHub workflow to also validate types

Notes

• We cannot update ESLint to version 10.0 because eslint-plugin-jsx-a11y does not support it. However, that package hasn't been updated in 1.5 years, so we may need to consider either removing it or finding a replacement.
• ts-node hasn't been updated in several years, do we need to switch to tsx?

After Merge

Remove the "Run ESLint + Prettier" check and add the "Run ESLint + Prettier + TypeScript" check in both the develop and main branch protection rules under "Require status checks to pass before merging" at https://github.com/UTDNebula/utd-trends/settings/branches.

looks good, I think we should migrate to tsx

[TyHil]

Cool, how about I add switching to tsx to the description of UTDNebula/nebula-library#11 so it can all be done at once (for Trends and Notebook). Then this can merge

[NishilJ]

sure
