chore: Update stable_abi.txt to the latest main

Source: https://raw.githubusercontent.com/python/cpython/main/Misc/stable_abi.txt

Remove a bogus unit test checking the input text file length.

The number of Stable ABI functions and globals has not changed.

+# For structs, one of the following must be set:
+# - opaque: The struct name is available in the Limited API, but its members
+#   are not. Users must manipulate it via pointers.
+# - members: Space-separated list of members which are part of the
+#   Limited API and Stable ABI.

 # Removing items from this file is generally not allowed, and additions should
