Rust: Generated comment on types has a typo

[jonjove]

Generated comments contain text like "is an XDR Struct defines as" which should read "is an XDR Struct defined as".

I believe you're referring to the Rust generated code and the following line, please correct me if I'm mistaken.

xdrgen/spec/output/generator_spec_rust/struct.x/MyXDR.rs

Line 972 in 4b3323b

// MyStruct is an XDR Struct defines as:

Should be fixable here:

xdrgen/lib/xdrgen/generators/rust.rb

Line 124 in 4b3323b

// #{name defn} is an XDR #{defn.class.name.demodulize} defines as:

That is correct.
