Formatting issues in metric docs
There are some formatting issues with the arguments (the incorrect blocks and apostrophes). I've yet to go through the whole metrics docs, noting them here as I find them for when I get a chance to fix them or if anyone wants to help!
Incorrect:
https://pytorch-lightning.readthedocs.io/en/latest/metrics.html#f1-func
https://pytorch-lightning.readthedocs.io/en/latest/metrics.html#fbeta-func
Correct examples:
https://pytorch-lightning.readthedocs.io/en/latest/metrics.html#iou-func
(among others)
Related: #4837
Edit:
Also noticed that F1 has an unused beta arg that shouldn't be there (we have fbeta), though that's probably a separate issue.
