feat(sourcemaps): Automatically insert Sentry Vite plugin in Vite config

[Lms24]

This PR adds automatic insertion of the Sentry Vite plugin into users' vite config files:

• Check if vite.config.(js|ts|cjs|mts) can be found
• If found, add plugin and import (magicast)
• If not found or error during insertion, fall back to copy/paste instructions
• Collect telemetry around sucess/failure of modification and failure reasons

closes #384

--notify seems to cause errors when running test:watch, so I disabled it
