To Update pytorch_to_onnx.py in blobconverter 8080

[dhruvmsheth]

While downloading ctdet_coco_dlav0_384 model from Luxonis:8080 port, it gives -

/usr/bin/python3: can't open file '/app/model_compiler/openvino_2021.3/pytorch_to_onnx.py': [Errno 2] No such file or directory

Also, to update Report a Bug link to correct link. Currently redirects to - https://gitlab.com/luxonis/blobconverter/-/issues/new

Seems like some public models in the Open_model_zoo in luxonis weren't available.
Eg -

[ ERROR ]  The "/tmp/blobconverter/f55d9a46a61a41ef9c7d380c6709caf2/efficientdet-d0-tf/efficientdet-d0_saved_model/efficientdet-d0_frozen.pb" is not existing file

Hi @dhruvsheth-ai,
Some of the models in public dataset had a preconversion step required in order to obtain their model files - this is now added to latest main (commit here) and deployed, so more networks from public dataset are available to download now.

Also, thanks for the report, I've assigned myself to this task so I remember to circle back - will look both at the incorrect link and ctdet_coco_dlav0_384 model download issue
