fix: linter error

This is showing up in an eslint build step in Electron:

> /__w/electron/electron/src/out/Default/gen/ui/webui/resources/cr_elements/preprocessed/cr_menu_selector/cr_menu_selector.ts
>   77:23  error  This assertion is unnecessary since the receiver accepts the original type of the expression  @typescript-eslint/no-unnecessary-type-assertion
>
> ✖ 1 problem (1 error, 0 warnings)
>   1 error and 0 warnings potentially fixable with the `--fix` option.

However, removing the assertion causes a typescript build failure:

> gen/ui/webui/resources/cr_elements/preprocessed/cr_menu_selector/cr_menu_selector.ts:77:23 - error TS2345: Argument of type 'HTMLElement | null' is not assignable to parameter of type 'HTMLElement'.
>   Type 'null' is not assignable to type 'HTMLElement'.
>
> 77         items.indexOf(this.querySelector<HTMLElement>(':focus'));
>                          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So I think the two different steps may be picking up typescript definitions.

This patch should be removed after the issue is tracked down
andfixed in a followup task.
