add TypeScript definition to task.js

Fixes error in IDE:

Fixes error in CI:

/.../cypress/plugins/index.ts
  13:3  error  Unsafe call of an `any` typed value  @typescript-eslint/no-unsafe-call

Workaround

I've been copy-pasting this between repos, which is a poor developer experience, but it's also now not working in monorepos, because it's existence in the root directory is not picked up by the workspace-specific linter.

declare module '@cypress/code-coverage/task' {
  import 'cypress';
  export default function registerCodeCoverageTasks(
    on: Cypress.PluginEvents,
    // eslint-disable-next-line @typescript-eslint/prefer-readonly-parameter-types
    config: Cypress.PluginConfigOptions,
  ): void;
}

The aim of this PR is to apply the workaround solution to this repository such that the workaround is no longer required.

Sorry to ping directly @lmiller1990 and @cacieprins but since you reviewed the last PR and this PR also has not been reviewed in >1 year, please give it a look. This TypeScript incompatibility blocks all validation of Cypress code coverage (which is important when combining multiple plugins) and linters that prevent the use of any.

@CharlesStover this is no longer an issue in Cypress 10+ AFAIK. Can you provide an example of this in a newer version of Cypress?

[lmiller1990]

Still an error @jordanpowell88

I added another PR tangential to this issue, as I don't think the type is 100% correct. Also, I stumbled upon this issue, which I think can be closed due to it already being resolved.
