fix(deps): declare StringDistances dependency

src/parsers.jl line 12 does `using StringDistances` but the package was
missing from Project.toml [deps]. Julia 1.11 precompile failed with:

    ArgumentError: Package InvestigativeJournalist does not have
    StringDistances in its dependencies

StringDistances is a registered package (uuid 88034a9c-...). Add it to
[deps] and constrain to compat = "0.11" (current major).
