Unify error condition for particles trail lifetime

[clayjohn]

Fixes: #79091

The error condition was 0.01 in the high-level nodes, 0.1, in the server, but the property only allows setting it as small as 0.01 with a granularity of 0.01. Accordingly, unify all places to use 0.01. I tested locally and while a value of 0.01 results in a very tiny trail, it still works fine.

This inconsistency appears to date back to when trails were first implemented 9005646

Property bindings for reference:

godot/scene/3d/gpu_particles_3d.cpp

Line 597 in 9d089fe

ADD_PROPERTY(PropertyInfo(Variant::FLOAT, "trail_lifetime", PROPERTY_HINT_RANGE, "0.01,10,0.01,or_greater,suffix:s"), "set_trail_lifetime", "get_trail_lifetime");

godot/scene/2d/gpu_particles_2d.cpp

Line 665 in 9d089fe

ADD_PROPERTY(PropertyInfo(Variant::FLOAT, "trail_lifetime", PROPERTY_HINT_RANGE, "0.01,10,0.01,or_greater,suffix:s"), "set_trail_lifetime", "get_trail_lifetime");
