Document binary size for mobile SDKS

[philipphofmann]

Core or SDK?

Platform/SDK

Which part? Which one?

All mobile

Description

Users keep asking what the binary size of the SDKs is. We have some automation calculating the size overhead for most of our mobile SDKs, which adds the size as a comment to PRs.

Suggested Solution

Ideally, we would update this data with every release in the docs, but we can start with putting a hard-coded value per SDK somewhere in the docs.

### SDKs
- [ ] https://github.com/getsentry/sentry-dart/issues/2437
- [ ] .NET
- [ ] Cocoa
- [ ] Android
- [ ] RN

We need to test whether dynamic linking has a different impact on the size.

Let's talk with Francesco from the web team - they did something similar (posting on GH release page). Also explain how the numbers are calculated.

As a first step: hardcode it and update it regularly.

Another option could be to update the release registry with the bundle size information, then it'd be automatically updated on the docs for every release.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
