Arachnid stomach yaml fix

Arachnids had their stomach `updateInterval` set to 1.5, 50% slower than
normal. But this doesn't actually slow down the speed that the stomach
digests things, only the rate at which it updates to check if enough
time has passed. (See https://github.com/space-wizards/space-station-14/blob/23f0b304f284d2600cb2c6b4c9d36fdca7f99ec4/Content.Server/Body/Systems/StomachSystem.cs#L57 )

This PR changes arachnid stomachs to have a `digestionDelay` of 30 (20
is default) to achive the desired effect.

Stasis beds are also bugged in a similar manner. They are intended to
slow down the digestion speed, but similarly all they do is change the
update rate. But fixing that requires actual code changes and is out of
scope for this commit.
