[MNT] Update dependency versions and complete migration to pyproject.toml (#596)

This PR updates the versions of outdated dependencies and migrates build
system to `pyproject.toml`.

Few Observations:
- `torch` still supports 1.X, but there is nothing about 2.X support. We
should see if it can support `torch` 2.6+ version completely or not.
- The project uses `pytorch-lightning`, I think we should move it to the
newer `lightning` version
- There are a lot of "core" dependencies. We should look how can we
reduce this stack.
Some dependencies which I think we should check if we could move to
`extras`:
   - `omegaconf`
   - `torchmetrics`
   - `tensorboard`
   - `protobuf`
   - `matplotlib`
   - `PyYAML`
   - `matplotlib`
   - `einops`
   - `fsspec`
   - `rich`
   - `ipywidgets`
- We should also create few more dependency categories in
`pyproject.toml`, like `docs` etc]
- We should also look into GH workflows, it is still using older python
versions
