Tedious v18 includes different TypeScript annotations

[Eldjotnar]

Installing the latest version of tedious (18.2.0) will result in a typescript error when creating a new MssqlDialect.

Type 'Connection' is not assignable to type 'TediousConnection | Promise<TediousConnection>'.
  Type 'Connection' is not assignable to type 'TediousConnection'.
    Types of property 'beginTransaction' are incompatible.
      Type '(callback: BeginTransactionCallback, name?: string | undefined, isolationLevel?: number | undefined) => void' is not assignable to type '(callback: (error?: Error | undefined) => void, transactionId?: string | undefined, isolationLevel?: number | undefined) => void'.
        Types of parameters 'callback' and 'callback' are incompatible.
          Types of parameters 'error' and 'err' are incompatible.
            Type 'Error | null | undefined' is not assignable to type 'Error | undefined'.
              Type 'null' is not assignable to type 'Error | undefined'.

If the proposed solution is just to add | null to the definition in mssql-dialect-config.d.ts, I'm happy to open a PR.

Hey 👋

PRs welcome. You'd also need to bump tedious dev dependency to latest.

I ran into this while trying to get started

@mjbergman92 same 😭 in the meantime I have to downgrade to tedious 16.4.0.

@Necrelox I reverted back to tedious@17 and I've had no issues so far.

@mjbergman92 I apologize for the late response. Thank you for your feedback!
