* Method Override Middleware for Hono.
*
* @see {@link https://hono.dev/docs/middleware/builtin/method-override}
*
* @param {MethodOverrideOptions} options - The options for the method override middleware.
* @param {Hono} options.app - The instance of Hono is used in your application.
* @param {string} [options.form=_method] - Form key with a value containing the method name.
* @param {string} [options.header] - Header name with a value containing the method name.
* @param {string} [options.query] - Query parameter key with a value containing the method name.
* @returns {MiddlewareHandler} The middleware handler function.
*
* @example
* ```ts
* const app = new Hono()
*
* // If no options are specified, the value of `_method` in the form,
* // e.g. DELETE, is used as the method.
* app.use('/posts', methodOverride({ app }))
*
* app.delete('/posts', (c) => {
*   // ....
* })
* ```
