Fix Handlebars benchmarks

[sebastienros]

Was wondering how this benchmark would not allocate as much as the others. It's actually not doing the same thing. The {{#truncate}} is not a thing unless implemented specifically.

Also changing the size of the list so the end result isn't too big. Will update the benchmark results in the other PR that has the charts.

As a matter of fact Fluid was not valid either ;)

Here are the new results. Also removing Liquid.NET since it's much slower and not in active development for a long time.
