Auto merge of #29623 - mrobinson:wpt-import-one-week, r=mukilan

Import WPT tests every week instead of every day

We often have multiple imports stacked up which makes it more confusing to land each one. In addition, giving a week to do the import will give us more margin to triage failing tests and hopefully to be able to use intermittent expectations for flaky tests.

<!-- Please describe your changes on the following line: -->

<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `___` with appropriate data: -->
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes do not require tests because this just change the frequency of a scheduled action.

<!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.-->

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
