Throughput tutorial

Layer / File(s)	Summary
Notebook dependency installation docs/customizer/tutorials/optimize-throughput.ipynb	Instructions and installation logic now use quiet %pip in the active notebook kernel.
Elapsed time calculation docs/customizer/tutorials/optimize-throughput.ipynb	get_elapsed_time subtracts updated_at from created_at and converts the duration to seconds.

- Line 888: Update the timing calculation in optimize-throughput.mdx to parse
created_at and updated_at into datetime values before subtracting them, matching
the notebook’s direct datetime-field subtraction behavior. Locate the relevant
step timing code and ensure it no longer treats either timestamp as a string.

Update docs/customizer/tutorials/optimize-throughput.mdx. It still parses created_at/updated_at as strings while the notebook subtracts the datetime fields directly, so the published tutorial keeps the wrong timing code.
