fix!: WithFee::with_fee method

[Roznovjak]

Description

fix WithFee::with_fee() method and also add without_fee() method.

https://github.com/galacticcouncil/HydraDX-node/blob/694cce69ee44890dcbd05c9ef1cd83079e3ce1ac/primitives/src/lib.rs#L121-L124

The current implementation computes value * (100% - fee_percentage) instead of value + fee

looks ok to me. but i am not very convinced that we need to update all versions of all pallets and runtime too.

I would just update the primitives crate version.

[Roznovjak]

What do you think @jak-pan ? It is a breaking change, but the affected method was never used before in the code( at least not in this repository).

[jak-pan]

Just runtime and impl_version in runtime. Where else is this used?

[Roznovjak]

We don't use with_fee() in our node repositories. We also need without_fee method in LBP so I have implemented it. I am not sure if I answered your question.

[jak-pan]

Only runtime then.

[Roznovjak]

I have reverted impl_runtime version to the previous one. The only version changes are now in primitives and runtime package.
