Update Vite & related packages

[CommandMC]

Direct updates:

• @vitejs/plugin-react-swc: 3.6.0 -> 3.9.0
• electron-vite: 2.0.0 -> 3.1.0
• vite-plugin-svgr: 4.2.0 -> 4.3.0

Important peer dependency updates:

• vite: 5.2.8 -> 6.3.5
• rollup: 4.17.2 -> 4.41.0

Note: I've removed our explicit vite dependency, since it's pulled in by electron-vite (& we only ever run Vite through electron-vite). This doesn't do much (we were already protected from peer dependency version mismatches by pnpm), but it makes the package slightly easier to update

I've tested starting the app normally (pnpm start) and AppImage & Windows builds on Linux. I don't think further testing is necessary, since the bundler should behave the same way on all platforms (and electron-builder wasn't updated)
