Update docs example versions to 1.3.2 (#24522)

## Summary

Updated all example version placeholders in documentation from 1.3.1 and
1.2.20 to 1.3.2.

## Changes

Updated version examples in:
- Installation examples (Linux/macOS and Windows install commands)
- Package manager output examples (`bun install`, `bun publish`, `bun
pm` commands)
- Test runner output examples
- Spawn/child process output examples
- Fetch User-Agent header examples in debugging docs
- `Bun.version` API example

## Notes

- Historical version references (e.g., "As of Bun v1.x.x..." or "Bun
v1.x.x+ required") were intentionally **preserved** as they document
when features were introduced
- Generic package.json version examples (non-Bun package versions) were
**preserved**
- Only example outputs and code snippets showing current Bun version
were updated
