Auto merge of #25287 - jdm:google-load, r=pcwalton

Disable H2 ALPN.

This was introduced by #24976, and it breaks loading https://google.com. Without any network specialists currently contributing to Servo regularly, I would rather revert the particular change that broke it rather than attempt to continue investigating.

---
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix #25286
- [x] These changes do not require tests because no H2 testing, no HTTPS configuration testing.

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