List Block: add type attribute for ordered list

[igorbenic]

Is your feature request related to a problem? Please describe.
I was writing a legal document and I could not choose if the list needs to be in numbers, words or any other type possible. I had to write the whole thing in one LIST block because there is no "start" option also.

Describe the solution you'd like
I would like to add attributes of an OL element as Block options so those are: reversed, type and start.

Describe alternatives you've considered
This can be done using the HTML of the block and changing it but this can be an issue when reloading the page since the save method might not take that into account.

And if you don't know HTML like regular users, there is no way of changing that.

This seems like something that could easily be added.

Hi @ellatrix does this mean we need to create list settings in the sidebar like below?

[ellatrix]

Exactly :)

@ellatrix I create a pr to fix this issue. There is still some work left to be done. I will continue to work on this. But I would really appreciate if you could provide some early feedback.

[ellatrix]

The attributes have been added except for type, which is a bit trickier. See #15113 (comment). I think it will require some core theme changes as well. :)

@Jackie6, thanks for working on this! My one note is that — for good accessibility — the Type control be a native selectbox component, similarly to how it’s used for the Image size and Default style selections.

I am interested in seeing the additional list types in Gutenberg, willing to help move this forward where possible, and learned that @Jackie6 has added this in this PR but it was later reverted before the PR was merged. @ellatrix asked for it to be made in a new PR which doesn't appear to have been made yet.

From the discussion on that PR (specifically this from @ellatrix , it sounds like the next steps that are needed going forward are:

• Confirm whether the selectors to be used are agreed upon
  (read for more context Add list start, reversed settings (in progress) #15113 (review))
  (These may already be agreed upon but I don't fully understand just yet. )
• Make a new pull request
• Make any relevant patches to Core

As mentioned above, @ellatrix had mentioned the ordered list styles to be made in a new PR, so I began to re-implement it but there have been quite a bit that has changed (files being moved, etc) in just a few months.

I think I figured out where and how to rewrite that code but there was code in packages/rich-text/src/component/editable.js

but that file has since been removed from Gutenberg (d9de027

Right now, I receive an ReferenceError that type is not defined. My code is at https://github.com/skorasaurus/gutenberg/tree/add/list-other-styles

Is it possible that this issue was already solved by:

• List block: Add numbering type selection #51186

[skorasaurus]

I think this can be closed because all of those features (what 'number' to start an ordered list, numbering style (Roman Number, and lower case roman numeral), and reverse order) have all been implemented in Gutenberg for some time.
