[nicksnyder]

As mentioned in this slack thread, it would be nice if sg setup worked on M1 machines so devs don't have to manually follow these steps.

Heads up @taylorsperry @pdubroy - the "team/dev-experience" label was applied to this issue.

@jhchabran we really need to finish up https://github.com/sourcegraph/sourcegraph/pull/25604 and get started on this 😬

[jhchabran]

• Puppeteer specific settings: will be fixed by https://github.com/sourcegraph/sourcegraph/pull/28783
  • Add a dependency on Rosetta (binary downloaded by puppeteer is still a x86_64) for macs running arm64 arch.
• Jaeger: PR that builds arm64 has been merged (Build binaries for darwin/arm64 jaegertracing/jaeger#3431), waiting for the next release.
  • Update the version so we get the one that has arm64 binaries available when it gets released.
• Drop the entire section.

Update: A new release of Jaeger is out that includes the PR, so we can fix this. https://github.com/jaegertracing/jaeger/releases/tag/v1.30.0

Closing this as https://github.com/sourcegraph/sourcegraph/pull/29815 shipped all the changes.
