Op.in operator doesn't work with array of dates.

Issue

Op.in operator doesn't work with array of dates.

Versions

• sequelize: 6.6.2
• sequelize-typescript: 2.1.0
• typescript: 4.2.3

Issue type

• [x] bug report
• [ ] feature request

Actual behavior

I have a table class with two primary keys, one being a date, the other a string. On the class I have an async function to fetch the latest data for the IDs by using the timestamp, which works using the Sequelize.Op.in operator.

Instead of getting the data, it errors in vscode,

Type '{ [Op.in]: Date[]; }' is not assignable to type 'string | number | bigint | boolean | Date | Literal | Fn | Where | Buffer | WhereOperators | WhereAttributeHash<any> | ... 6 more ... | undefined'.
  Types of property '[Op.in]' are incompatible.
    Type 'Date[]' is not assignable to type 'string | number | bigint | boolean | Date | Literal | Fn | Where | Buffer | WhereOperators | WhereAttributeHash<any> | ... 7 more ... | undefined'.
      Type 'Date[]' is not assignable to type 'WhereAttributeHash<any>'.
        Index signature is missing in type 'Date[]'.ts(2322)

Expected behavior

I expect the [Op.in] operator to work with an array of dates.

I found it didn't work with bigint as well.
