fix: exported model name should match generator class name

[roedoejet]

PR Goal?

When you run everyvoice export the vocoder HiFiGAN is exported as a HiFiGANGenerator which then breaks the model name validation.

Fixes?

I just fixed the bug before creating an issue report since I just noticed it this weekend.

Feedback sought?

@SamuelLarkin - I'm not sure if the quick fix I've done here is the best way of addressing this, can you please advise if there is another place I should address the fix?

Priority?

high - currently demos are broken with exported vocoders

Tests added?

I can't really test the exporting of a model because of the size of the vocoder model (1GB)

How to test?

Confidence?

Version change?

Samuel and I reviewed this together, and we agree it is implemented correctly, but there is some refactoring we want to apply before merging. PR coming soon for that.

@roedoejet Please review EveryVoiceTTS/HiFiGAN_iSTFT_lightning#43 and #595
Sam and I agreed this PR here was conceptually OK but needed refactoring before merging.

[joanise]

Looks good, works correctly, I'll merge #595 at the same time.
