[docs] add possible error codes & docs on what they mean

[sakulstra]

Started integrating paraswap into our application & want to ahndle errors properly.
Would be great if the docs would contain a list of possible error codes & a short explanation on what they mean.

Till now i only faced:
ESTIMATED_LOSS_GREATER_THAN_MAX_IMPACT, but I'd assume there are more.

nothing...

Is there an update on this one or would you explain that error a bit more in detail please.

Hello, we documented all the errors in our OpenAPI specification right here : https://app.swaggerhub.com/apis/paraswapv5/api/1.0#/TransactionsErrorMessage (accessible from the docs https://developers.paraswap.network/ then go to > Try OpenAPI specification).

Maybe I'm missing something but I only see an array of non-explanining messages:

E.g. can you point me specifically to the documentation of the aformentioned ESTIMATED_LOSS_GREATER_THAN_MAX_IMPACT error?

Any updates?
