Auto merge of #29610 - mrobinson:notify, r=mukilan

Use notify-py to send notifications

- Use notify-py to send notifications, but use a custom notifier on
  Linux since transient (ie non-sticky) notifications are not supported.
- Add an icon to the notification.
- Don't send a notification after doing `./mach check` because that
  can trigger notifications when `rust-analyzer` is working.

<!-- 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 they just change build notifications.

<!-- 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. -->
