Default particle speed (extra) should be set to 0 instead of 1

Expected behavior

Particle speed should default to 0, NMS code for the particle command, with only a name and position argument, is:

Commands.argument("pos", Vec3Argument.vec3())
    .executes(
        context1 -> sendParticles(
            context1.getSource(),
            ParticleArgument.getParticle(context1, "name"),
            Vec3Argument.getVec3(context1, "pos"),
            Vec3.ZERO,
            0.0F,
            0,
            false,
            context1.getSource().getServer().getPlayerList().getPlayers()
        )
    )

Observed/Actual behavior

Spawning a particle with the API defaults the extra (speed) field to 1. paper-server code:

and

This results in some of the particles to appear "aggressive" shooting off into the distance.

Steps/models to reproduce

Spawn a particle affected by speed like FLAME or CLOUD

Start with paper-server/src/main/java/org/bukkit/craftbukkit/CraftWorld.java and paper-server/src/main/java/org/bukkit/craftbukkit/entity/CraftPlayer.java at the linked particle methods. Compare their default extra value with the NMS particle command shown in the issue, then reproduce with FLAME or CLOUD. Done means API particle spawning defaults the extra speed value to 0 rather than 1.
