Dependency health/cleanup #26187

Problem Statement

This isn't quite a "feature request" but you have no valid template I can use.

#26186 was abruptly closed without much explanation, so this is the issue to track the suggestion rather than jumping straight to a PR.

I'd like to suggest doing some general tidying of dependencies:

• Remove any which are made redundant by native functionality
• Remove any unmaintained dependencies that have widely used alternatives
• Remove any oversized dependencies that have widely used alternatives

The reasons are generally as follows:

• Increased supply chain security as there will be fewer dependencies, particularly fewer unmaintained dependencies
• Decreased install size
• Modernised dependencies (e.g. more ESM, less CJS)

Solution Brainstorm

Audit each of the monorepo's package.json for any dependencies that can be replaced. Ignoring opinionated switches for now, only focusing on those which are redundant, unmaintained, or oversized.

Additional Context

I spend a lot of my time working on widely used JS packages and tools to help improve the supply chain health. I've been doing this for many years across the ecosystem as a whole, and it'd be nice to apply some of that to sentry's packages too.

All of the suggestions/findings will result in a lighter weight package for both sentry maintainers and consumers, too.
