Description
When running the "select by attributes" algorithm without a value filled, you get a warning that there's a wrong or missing value for the value parameter.
In the "Extract by attribute" case, the "Value" parameter is indicated as optional and you can run the algorithm without it, returning a layer with zero feature.
Other than not being consistent with the corresponding "select by..." alg behavior, I fail to see why someone would like to run a conditional algorithm without filling a condition.

because it's not needed to run null checks (fixes #19469 which is actually reported in the wrong way)
