fix: the current type module path confusing typescript tsc

[tawago]

Description

Resolves:

• Strange type issue #1015
• What is the purpose of redeclaring @docusaurus/plugin-content-docs types as @docusaurus/plugin-content-docs-types? #974

Motivation and Context

The type error:

node_modules/docusaurus-plugin-openapi-docs/src/types.ts:24:8 - error TS2307: Cannot find module '@docusaurus/plugin-content-docs-types' or its corresponding type declarations.

24 } from "@docusaurus/plugin-content-docs-types";

is really confusing because it seems like an official @docusaurus package in https://github.com/facebook/docusaurus/tree/main/packages but it's not. It gives an extra hurdle for typescript to resolve types.

NOTE: This PR does not address:

node_modules/docusaurus-plugin-openapi-docs/src/types.ts:8:32 - error TS2307: Cannot find module '@docusaurus/plugin-content-docs/src/sidebars/types' or its corresponding type declarations.

8 import { SidebarItemDoc } from "@docusaurus/plugin-content-docs/src/sidebars/types";

as "moduleResolution": "node" can solve it.
