chore: Remove support for brotli chunk compression (#2973)

### Description
It appears we have never supported `brotli` server-side so there is no reason to support it in the CLI, either.

### Issues
- Resolves #2808
- Resolves [CLI-174](https://linear.app/getsentry/issue/CLI-174/remove-brotli-support-for-chunk-uploads)
