@miniflare/shared should not depend on @types/better-sqlite3

[FlatMapIO]

Although I've already included vitest-environment-miniflare/globals in types:

"types": [
  "@cloudflare/workers-types/2023-07-01",
  "vitest-environment-miniflare/globals"
]

But in vscode, the worker api still points to @types/node #761.

I looked up the following dependency via pnpm why @types/node.

vitest-environment-miniflare 2.14.2
├─┬ @miniflare/queues 2.14.2
│ └─┬ @miniflare/shared 2.14.2
│   └─┬ @types/better-sqlite3 7.6.9
│     └── @types/node 20.11.17

I think we should avoid introducing it to prevent type problems.
