Moving Site Deployment script to GHA

[osalpekar]

We are moving all jobs to GHA across the PyTorch organization. This PR does this for the site deployment CCI job that exists in the pytorch.github.io repo. Note that this does not use caching in its current form - we can likely do this in a follow-up.

WIP: testing this without breaking anything

We should also add deprecation of circleci workflow: https://github.com/pytorch/pytorch.github.io/blob/site/.circleci/config.yml

LGTM

Hi @osalpekar, I've deployed a change to the PyTorch website but it is not building as expected. Any ideas why?

[osalpekar]

Looks like the push is still failing for GHA job on trunk, which is why the site is not getting built as expected. I'm going to bring back the CCI job temporarily until we can figure out the GHA issue.

@osalpekar when you did the migration, have you added the secrets to the workflow?

[osalpekar]

@malfet Yes, that's done here: https://github.com/pytorch/pytorch.github.io/blob/site/.github/workflows/build.yml#L16.

I remember seeing something like that in the past. Will push the fix once find out what was it

Ok, two things were missing:

• Pass secrets to composite workflow 8bae164 (as shown in this test https://github.com/pytorch/test-infra/blob/ed7237ab9f23fa1b2f29699cf75d85b4a2a590a5/.github/workflows/test_linux_job.yml#L25 )
• Prefix name with SECRET_ as shown in the abovementioned test 2a26558
