Due to issue #11567, Alternator do not yet support adding a GSI to an
existing table via UpdateTable with the GlobalSecondaryIndexUpdates
parameter.
However, currently, we print a misleading error message in this case,
complaining about the AttributeDefinitions parameter. This parameter
is also required with GlobalSecondaryIndexUpdates, but it's not the
main problem, and the user is likely to be confused why the error message
points to that specific paramter and what it means that this parameter
is claimed to be "not supported" (while it is supported, in CreateTable).
With this patch, we report that GlobalSecondaryIndexUpdates is not
supported.
This patch does not fix the unsupported feature - it just improves
the error message saying that it's not supported.
