Bump ACTS to v40.0.1

Release notes are here: https://github.com/acts-project/acts/releases/tag/v40.0.1

This should fix the issue seen in https://its.cern.ch/jira/browse/ATLINFR-5717 where ACTS fails to configure on aarch64 on Linux. No other changes are introduced.

For reference: @cvarni @ncalace @sabidi @jdandoy @christos @dshope @jmasik @astefl @adye @pibutti

I'm skipping the full-build and test labels, because there are no code changes at all in this tag, the only difference is in CMake.
