Sidebar Navigation Shows Duplicate Sections for Multi-Language Docs

[soniasingla]

The sidebar navigation (table of contents) shows duplicate sections and method names on documentation pages that use multi-language code examples.

Steps to Reproduce

1. Go to https://www.inngest.com/docs/learn/inngest-steps
2. Look at the right-hand sidebar and it shows all sections from all languages (TypeScript, Go, Python) variants are rendered in the sidebar simultaneously

Expected Behavior

The sidebar should:

1. Show only one "Available Step Methods" section
2. Dynamically update method names in the sidebar when switching between language tabs
3. Display TypeScript methods when TypeScript tab is selected, Go methods when Go tab is selected, etc.

It should look something like:
