Revert 22.3.2 increase to infested spawns

[dopey_opi]

So far the Plague Star event is living up to its name.

Fishing and mining are currently being plagued by a near constant stream of low-level infested spawning near me.  They're too low level to offer any actual challenge, and they mostly just annoy the hell out of me.  Good cuts on ore being messed up, and you may as well give us sharkwing on PoE because if one dares to try and fish as anything other than Atlas you're going to end up knocked in the water about once every two seconds.  It's completely obnoxious.  We don't need little bands of 3-5 lv20 trash mob infested spawning behind us to remind us that there's an event going on.  We do other things in PoE besides Plague Star missions.  Please reduce the amount of interruption because it's annoying as hell.

already the grineer was way too many and way too clsoe to the water, fishing was already a pain but now is just painful, you can't do anything whitout have horde of evenmy on you killing the fish... we already have to waste time for create the bait and now we have to hope that we can fish with only 10 enemy bothering us... otherwise...

Or just make tenno/warframes non-hostile when wielding fishing spears and mining lasers

It's annoying for sure. Even invisibility won't stop them from beelining to where you are.

Conspiracy: now that Bounty rewards are stage-by-stage, annoy playerbase enough for them to buy Gara to Mass Vitrify block Infested.
