Bumped scipp to 23.08

[andped10]

New version of scipp uses plopp as default plotting tool.

plot.py

• plopp doesn't allow for variance in coords data.
• changed to one argument per line (easier to see differences in git)
• removed try / expect to handle code logic

In pyproject.toml:

• bumped scipp to 23.08
• dev dependencies
  • alphabetic order
  • added plopp

Adjusted jupyter notebooks to new plotting functionality.

Adjust read in data to the more strict requirements by scipp (removed plural s in example data)

Looks good. Two minor issues raised, once resolved the branch can be merged.
