Ebrehault listing block

[ebrehault]

Naive implementation.

Comments:

• The call to collect the items is done directly in apps/seven/app/root.tsx, not sure if that's accurate
• I have changed the BlocksFormData type as followed:

export type BlocksFormData = ListingBlockFormData | DummyBlockFormData;

That way we can have a specific typing for each type of blocks instead of having one generic interface with a very unhelpful [x: string]: unknown;. DummyBlockFormData is there for now as the other specific block types are not existing yet, but it is meant to be removed once everything is properly typed.

I changed the base branch to seven instead of main.

I think my PR is ready.

Last questions:

• not sure why packages/plate/output.css got modified, I did commit it, but not sure I had to
• when adding catalog dependencies in the different packages with pnpm add react-i18next@catalog: --filter @plone/blocks, I saw pnpm-workspace.yaml was modified automatically. My understanding it should not, because catalog is managed in catalog.json. What is the proper pnpm command?
