[TASK] Implement `@typescript-eslint/no-array-delete` rule

The eslint configuration now takes the rule
`@typescript-eslint/no-array-delete` [1] into account, prohibiting
element removal from an array via `delete`. The problem with `delete` is
that the element to be removed is in fact replaced with an `empty` slot,
effectible keeping the array's size. Using `splice()` [2] is the
preferred way to remove elements from an array.
