blobOptionsGetter shouldn't have a default to API

[pionxzh]

When I import markdown by:

const contentParser = new ContentParser(page)
const pageBlockId = page.addBlock('affine:page')
const frameId = page.addBlock('affine:frame', {}, pageBlockId)
contentParser.importMarkdown(markdown, frameId)
//             ^^^^^^^^^^^^

If there are any image element, it will automatically call workspace.blobs (the BlobStorage) to store the blob.

But the default value of _blobOptionsGetter caused the parser to send a request to /api/workspace/{workspace_id}/blob to persistent the blob on the server, which shouldn't be enabled by default.

See

blocksuite/packages/blocks/src/__internal__/content-parser/parse-html.ts

Line 468 in c673f66

const id = await storage.set(imgBlob);

blocksuite/packages/store/src/workspace/workspace.ts

Lines 35 to 37 in c673f66

	private _blobOptionsGetter?: BlobOptionsGetter = (k: string) =>
	({ api: '/api/workspace' }[k]);

Current workaround

const workspace = new Workspace({
    id: workspaceId,
    providers: [],
+   blobOptionsGetter: () => undefined,
})
