Optionally disable enforcement of trailing zeros in float literals

[serenity4]

Having trailing zeros in floats is mostly a matter of style, and would IMHO fit very well as a parameter to be configured in a .JuliaFormatter.toml. If there is any chance to expose it, it would be very much appreciated!

I think something similar to the trailing_comma option could work. You could also get very granular and have one option for leading 0s and one for trailing 0s
