fix(balance): fix pistol accelerator needing more wire than rifle, make it coilgun addon

[DoubleBullfrog]

• I wrote the PR title in conventional commit format.
• I ran the code formatter.
• I linked any relevant issues using github keyword syntax so it can be closed automatically.
• I have committed my changes to new branch that isn't main so it won't cause conflict when updating main branch later.

Purpose of change

These gunmods are pretty clearly coilgun addons and not railguns, given the amount of copper wire and lack of rails in the recipe, as well as the ability to be mounted on shotguns.
The pistol addon required 500 copper wire and the rifle addon required 100, which is obviously backwards.

Describe the solution

Change the description and swap the amount of copper wire required for the rifle/pistol gunmods.

Describe alternatives you've considered

Not caring about the distinction between a coilgun and a railgun.
