[Typo] Typo in the Patch JSON and in the code

[Miniontoby]

I found this typo in the Patch data JSON that can be generated, and apperently it is also inside the code:

VR-Stage-Lighting/Packages/com.acchosen.vr-stage-lighting/Editor/VRSL_FixtureDefinitions.cs

Line 10 in 12dedbe

public struct FixtureDefintion

FixtureDefintion -> FixtureDefinition

It confused me that it was misspelled in the patch JSON file, that I got from a mapmaker.
