Update Variable Names to be Consistent with Updated Jedi Hashes

[JingCheng-NOAA]

Recent JEDI hashes update has multiple variable name changes.
A recent test with updated satwind yaml file indicates that tsea is no longer used inside JEDI. If remove this variable from state variable list, the an error Field_fail: Field water_area_fraction cannot be obtained from input fields..
However, if replace this name with sea_surface_temperature, JEDI will look for sst in restart file.
If replace this name with skin_surface_temperature, JEDI will look for ts in restart file. But none of sst or ts exist in restart file.

Fixed with two minor changes: 1) replace tsea with skin_temperature_at_surface in state variables; 2) add following in restart.yaml

- long name: skin_temperature_at_surface
  io name: tsfc
  io file: surface

Above changes will be included in the next HDASApp updates.

According to GDASApp recent update, the variable tsea is replaced by tmpsfc, which is represent the skin_temperature_at_surface in history file. However, in HDASApp, we do not use history file but restart file, in which there is no variable named as tmpsfc.

Modified the gfs-restart.yaml with following, and solve the warning issue.

- long name: skin_temperature_at_surface
  io name: tsea
  io file: surface
