[Admin Extension Docs] Add resourcePicker to Action Extension Api docs

[melissaluu]

Do Not Merge: Will need to rebase after #2379 ships so we can update this PR to include the GenericPicker being available in ActionExtensionsApi

Background

Related to https://github.com/Shopify/app-ui/issues/1756
Should ship after https://github.com/Shopify/web/pull/146520 and #2379
Follow up shopify-dev PR https://github.com/Shopify/shopify-dev/pull/50766

Add resourcePicker and genericPicker Api to Action Extension Api to support the new Resource Picker availability in action extensions.

Solution

Update the ActionExtensionApi interface to include the ResourcePickerApi and GenericPickerApi

NOTE: Will need to check on https://github.com/Shopify/shopify-dev/pull/49753 to see if there's verbage we'll need to update in https://github.com/Shopify/ui-extensions/blob/unstable/packages/ui-extensions/docs/surfaces/admin/staticPages/admin-extensions.doc.ts so it doesn't say blocks only.

We detected some changes in packages/*/package.json or packages/*/src, and there are no updates in the .changeset directory. If the changes are user-facing and should cause a version bump, run yarn changeset to track your changes and include them in the next release CHANGELOG. If you are making simple updates to repo configuration, examples, or documentation, you do not need to add a changeset.
