fix: Add missing name tag to schema annotations.

Without this tag, we get errors like google/adk-java#152

I disagree with this. This repetiion should not be required; see google/adk-java#152 (comment).

Currently, you have to 1) either provide a name attribute, or indeed 2) use -parameter.

I didn't check, but if name is always required, regardless of whether the user specifies -parameter or not, then I would think it's a bug.

IMHO the logic should be: if the name is specified, use it (as you may want to override the actual parameter name), or else if the name can be found by reflection (because -parameter is set) then use that, otherwise throw an error.

Historical notes: A bit before the release of 0.1.0, no error was thrown when the name attribute wasn't specified. But if -parameter wasn't set, a generic name like arg0 was used instead.
