Bug with decimal precision example

[sergii]

https://rails.help provides wrong example:

bin/rails g model ExampleModel other_model:references{polymorphic}:uniq lng:decimal{10,6}

right example:

bin/rails g model ExampleModel other_model:references{polymorphic}:uniq lng:decimal{10-6}

Please change decimal{10,6} to decimal{10-6}

Thanks for bringing this up @sergii! This is actually what the docs recommend. I think it might have something to do with the shell rails/rails#13520 (comment) (mine does the same too, for what it's worth).
