As seen in multiple PRs that renovate raised today, the @testing-library/ packages are not bundled in the 'packages:jsTest' pre-defined group. As they aren't relevant to be separated, this commit changes the config of renovate to treat them as one big PR in the future.
* Updated schedule of renovate
Even if renovate only creates 1-2 pull requests per day, they start to become annoying. Therefore, we decided to limit the timeslot for renovate actions to our dependency-patch-day Saturday.
* Added option to remove the hourly limit
Because we extend config:base we have a default hourly limit of 2. This change sets that to 0 and thereby disables the limit.
