ci: update pullapprove groups and add docs

[IgorMinar]

With this update to permissions the docs team can easily identify the technical reviewer for a particular doc, which should streamline the reviews.

I also added Jennifer into all groups that contain docs, so that she can approve changes that contain only editorial changes.

Closes #21692

I see that you just added the PR action: merge label, but the following checks are still failing:
     missing required status "code-review/pullapprove"
     status "ci/circleci: lint" is pending
     status "ci/circleci: test_ivy_aot" is pending
     status "ci/circleci: build-packages-dist" is pending
     status "ci/circleci: test_ivy_jit" is pending
     status "ci/circleci: test" is pending
     status "continuous-integration/travis-ci/pr" is pending

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken master, please try rebasing to master and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.
