v5.6.0: uninitialized constant Liquid::StrainerFactory (NameError)

[rocket-turtle]

Just want to open this issue if someone stumbles across the same error. Im not sure if StrainerFactory was an internal class. We only uesed it in one test.

There is a breaking change in v5.6.0

• Removed StrainerFactory in favor of Environment-based strainer creation

The StrainerFactory got deprecated and removed in the same version
