[Reland] Use head sha timestamp as end date for similar failure search (
45e6a91 
#5160)

The context is in #5151. This
reland PR adds 2 more fixes:

* Do a left join from `workflow_job` to `push`, so that Dr.CI can always
find all the jobs from the PR even when the commit SHA is not found on
`push` in the case of forked PRs. The `head_sha_timestamp` field will be
empty then.
* When the `head_sha_timestamp` is empty, call `fetchCommitTimestamp` to
get the timestamp directly from GitHub. This is done once per commit.

Note that if the GitHub query fails and `head_sha_timestamp` is still
empty. Dr.CI won't apply similar flaky search to avoid FP, the search
query would expand to the current date otherwise.

### Testing

```
curl --request POST \
--url "http://localhost:3000/api/drci/drci?prNumber=PR_NUMBER" \
--header "Authorization: TOKEN" \
--data 'repo=pytorch'
```

1. pytorch/pytorch#125271, new forked PR, no
ciflow. `head_sha_timestamp` from Rockset is empty and
`fetchCommitTimestamp` is invoked. Dr.CI continues to work.
