Update tutorials to work with current versions

[perrygreenfield]

Changed the installation within the converter tutorials to use pyproject.toml

Fixed various formatting issues.

Removed code that was supposed to restart the kernel from executing a cell, that doesn't appear to work anymore; now the user is instructed to do that through the notebook interface.

Changed the use of a keyword "type" to "type_"

Thanks for making these updates. The converter notebooks failed for me.

It looks like they're dumping file in ~ then trying to install it. It failed for me with:

The notebook cell it generated won't scroll (aren't notebooks great...) so I'm not sure what all went wrong there. Can we update this to instead use files that are already included in the repository (instead of using %%writefile?

For the other notebooks I had to install:

• asdf
• astropy
• asdf-astropy
• gwcs
• matplotlib

to avoid crashes. Is this documented anywhere?

I'm going to merge this and address the above issues in follow-up PRs.
