Move MikeGoldsmith to emeritus

[MikeGoldsmith]

Changes

I was part of the original group who helped get this project going and such was added as an approver. I haven't been involved in this group for a while so should be removed from the @open-telemetry/rust-approvers group.

This PR moves myself to Emeritus group in Contributing file too.

Merge requirement checklist

• CONTRIBUTING guidelines followed
• Unit tests added/updated (if applicable)
• Appropriate CHANGELOG.md files updated for non-trivial, user-facing changes
