We were seeing actions failures where the cache would be restored
"successfully" but then "Install CircuitPython deps" would fail:
# Step "Fetch IDF tool cache"

/bin/tar -xz -f /home/runner/work/_temp/a990f24d-c365-4685-b739-10e052812c81/cache.tgz -C /home/runner/work/circuitpython/circuitpython/.idf_tools
Cache restored from key: Linux-idf-tools-731ed12bcdfbfa8b5dd37e03703992271b3ce85dd629e45130f80f43b84ce3a8

Adding ESP-IDF tools to PATH...
Not using an unsupported version of tool cmake found in PATH: 3.17.0.
I checked locally, and (even when dist/* is removed) it is very quick to
run each of the `idf_tools install` steps, about 2s total.
Try doing this to see whether it fixes the CI problems.
