Auto merge of #12200 - aneeshusa:add-linux-dev-yaml, r=larsbergstrom

Add linux dev yaml

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

Sync `steps.yml` from saltfs and add `linux-dev-yaml` builder for testing steps.yml switchover. Helps with servo/saltfs#316.

---
<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [ ] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [ ] These changes fix #__ (github issue number if applicable).

<!-- Either: -->
- [ ] There are tests for these changes OR
- [x] These changes do not require tests because linux-dev-yaml is non-gated and other changes are running in production

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

<!-- Reviewable:start -->
