Add hyperfine installation instructions; update hyperfine code samples (#13034)

## Summary

When following the step-by-step instructions to run the benchmarks in
`CONTRIBUTING.md`, I encountered two errors:

**Error 1:**
`bash: hyperfine: command not found`
    
**Solution**: I updated the instructions to include the step of
installing the benchmark tool.

**Error 2:**
```shell
$ ./target/release/ruff ./crates/ruff_linter/resources/test/cpython/ 
error: `ruff <path>` has been removed. Use `ruff check <path>` instead.
```
**Solution**: I added `check`.

## Test Plan

I tested it by running the benchmark-related commands in a new workspace
within GitHub Codespaces.
