Remote functions doc & types tweak

[jycouet]

With the type update, userland can do: (like in the doc)

-{#each createPost.fields.title.issues() ?? [] as issue}
+{#each createPost.fields.title.issues() as issue}
  <p class="issue">{issue.message}</p>
{/each}

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

• It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.

Edits

• Please ensure that 'Allow edits from maintainers' is checked. PRs without this option may be closed.

this is supposed to be turning markdown to HTML — without it, it would just display the exact thing that's already in the <textarea>

renderMd is ugly!

I just don't know how to say: It's not from svelte

[Rich-Harris]

i don't think we want this! at the moment !field.issues() serves as a proxy for 'is valid', which would no longer be true if it always returned an array

[jycouet]

I see.
Maybe adding in docs ?? [] then?

[Rich-Harris]

see #14628 (comment) — you can use it without the ?? [], it causes squigglies at the moment but we can fix that

Perfect
