[MC-271901] Entity effect "play_sound" Field "pitch" value upper limit is 1.0 instead of 2.0

Despite the changelog says pitch value upper limit is 2.0, if pitch value greater than 1.0 game will report errors.

It works if you use a map

"pitch": {
    "type": "minecraft:uniform",
    "min_inclusive": 1.5,
    "max_exclusive": 1.6
}

but I think apparently using a single number actually creates a range from N to N+1 for some reason? I can't imagine that's intended for this field
