Describe the bug
Following link is not correct: https://docs.monai.io/en/latest/modules.html#lamp-large-deep-nets-with-automated-model-parallelism-for-image-segmentation

This link is defined here:

MONAI/docs/source/modules.md

Lines 154 to 155 in cdac033

	having flexible memory requirements (_alternatively, please check out the latest research on [model parallel
	training](#lamp-large-deep-nets-with-automated-model-parallelism-for-image-segmentation) using MONAI_). It also supports

To Reproduce
Steps to reproduce the behavior:

1. Go to https://docs.monai.io/en/latest/modules.html#sliding-window-inference
2. Click on "model parallel training"

Expected behavior

I also found this link which doesn't work:

MONAI/docs/source/modules.md

Line 59 in cdac033

Implementations are provided to ensure optimal usage of the underlying hardware resources. [[fast training guide]](https://github.com/Project-MONAI/tutorials/blob/main/acceleration/fast_model_training_guide.md)

For some reason it links to
https://github.com/Project-MONAI/tutorials/blob/main/acceleration/fast_model_training_guide
which misses the .md at the end. It should point to
https://github.com/Project-MONAI/tutorials/blob/main/acceleration/fast_model_training_guide.md

See also here: https://docs.monai.io/en/latest/modules.html#gpu-based-accelerations

Also some tutorial links are referencing the master branch, which was renamed to main.
You can still open the links but they show a warning e.g.
https://github.com/Project-MONAI/tutorials/blob/master/acceleration/dataset_type_performance.ipynb

Hi @Shadow-Devil ,

The issue "missing .md" in the link may be related to the building of API doc web page.
Welcome a contribution to fix it. An easy way is to use the explicit link YYY in the doc instead of [XXX](YYY).

Thanks.
