Missing dependency on wget

[moble]

I ran into a tricky bug because I didn't have wget installed in the conda env that I had installed gwsurrogate into, so when it tried to download the surrogate data, that command errored out. (It errored silently, which is a different issue: sxs-collaboration/gwsurrogate#18.) So this package should also depend on it; wget should be added to this list:

gwsurrogate-feedstock/recipe/meta.yaml
