Upgrade packages based on dependabot recommendations

[huang0h]

Why

A decent number of packages used here haven't been upgraded in years, and security flaws have been identified in them over time. Upgrading any outdated/vulnerable packages will make our app more secure (and maybe give us some nice extra features to use)

What to do

• Go through the existing security issues identified by dependabot and identify which packages need to upgraded (and to what version) to resolve any security issues
• Upgrade as many as possible while making sure we don't introduce any dependency conflicts and that the app still builds and works fine
