lib/matplotlib/tests/test_inset.py: Fix tolerance on aarch64

apatard · apatard · commit 8d4b92c39cdc · 2026-04-07T15:55:59.000+02:00
I tried to run the test suite on a aarch64 linux system and it failed
due to test_zoom_inset_connector_styles exceeding the tolerance.
The test is already checking the platform to increase the tolerance
on aarch64 but the check is failing as on this system,
``platform.machine()`` is returning ``aarch64`` not ``arm64``.

I've checked on several distributions and it seems consistent.

So, update the check to match both ``arm64`` and ``aarch64``.
