Support T5 loras for Flux

[christopher5106]

Some new Loras have trained T5 lora weights:

For example: https://civitai.com/models/1022387/randommaxx-illustrify

Following discussion in #10745

That's not a trained T5, that's leftover garbage from a comfy merge

Check the values. They are all zero:

thanks for your further investigation.. I will close the issue since under 9000 loras I don't see any other trained T5 otherwise.
