Fixes a regression on seeding introduced by
https://github.com/twentyhq/twenty/pull/16296.
In the seeding process an async function was used without awaiting. This
caused all the seeded configs to be empty.
Note: The need to await is because `transformRichTextV2Value` is async
due to `const { ServerBlockNoteEditor } = await
import('@blocknote/server-util');`. @etiennejouan do you know why is it
done this way? Is it to reduce bundle size? Would it be possible to
create another util which is not async and which imports
`@blocknote/server-util` at the top?
