Nerf the Seraphim T3 Subhunter and make larger formations of it less oppressive pt. 2

[Basilisk3]

Description of the proposed changes

Continuation of #5895, which was a step in the right direction but ultimately only nerfed the unit from being the best unit in the game down to S-tier.

Yathsou: T3 Submarine Hunter
(XSS0304):

• Physics
  • MaxAcceleration: 6 --> 5.5
  • MaxBrake: 6 --> 5.5
  • MaxSpeed: 5 --> 4.6
  • MaxSpeedReverse: 5 --> 4.6
  • MaxSteerForce: 5 --> 4.6
• Uall Cavitation Torpedo
  • Range: 65 --> 60

Testing done on the proposed changes

Tech 2 subs have a much easier time catching Yathsou's but more testing is needed.
