Fixes not all escape pods arriving to escape pod shuttle at round end

[aramix273]

About The Pull Request

a new escape pod shuttle was introduced with #11150, however the ids of the escape pod docks in it were not tweaked to match those of their respective escape pods (had pod_2_away instead of pod2_away for example); this PR changes just that

this caused multiple identical runtimes (Runtime in docking.dm,4: Cannot read null.docked) because new_dock argument would be null (from SSshuttle.getDock("pod2_away") which could not find said dock and returned null), and these should now be solved

Why It's Good For The Game

allows more than one escape pod to make it to escape pod shuttle (and probably counts towards escape objective)
fixes #11374

Testing Photographs and Procedure

Screenshots&Videos

tested on Meta Station with 3 escape pods
