[webkit-dev] Announcing Login with GitHub on EWS webpages

One cool trick can be to combine this feature with "skip-ews" GitHub label (or --no-ews flag in git-webkit, announced in https://lists.webkit.org/pipermail/webkit-dev/2023-January/032461.html).

For example, if you want to run EWS only on certain queues (e.g.: while debugging/iterating on a particular platform), you can create the PR with "git-webkit --no-ews", once most of the queues have processed the PR and skipped it, you can remove the 'skip-ews' label from GitHub UI, click on specific status-bubbles for the queues you want to run EWS on, and then click "Rebuild" for those skipped builds. That way you could run EWS on specific queues.

Also, please note that the word 'Rebuild' and "Builder" comes from buildbot terminology, and might be little confusing for some of us, as we use terminology of "Builder" and "Tester" queues which means building WebKit and running tests. However, buildbot refers any queue as "Builder', and it refers retrying an EWS run as "Rebuild". Pressing "Rebuild" button on a tester queue (e.g.: webkitpy-ews) might not involve building WebKit or anything.

Please let me know if anyone has any question.

> In Bugzilla world, we have a feature named "Retry failed builds" which allow us to retry the EWS builds which failed (especially useful when the failure might be due to flakiness or infrastructure issue). However, in GitHub world, there was no way for WebKittens to retry the builds.... until now.
> From now on, when you visit any ews-build.webkit.org page (e.g.: the page which opens on clicking on any EWS status-bubble), you would be able to login to it using your existing GitHub account. To login, on any ews buildbot page, simply click on "Anonymous" -> "Login with GitHub" (on top-right). You will need to authorize "WebKit EWS" to access your GtiHub account to Login.
> After login, any WebKit contributor (listed in https://github.com/orgs/WebKit/teams/contributors/members) can press "Rebuild" button on any build. This would provide ability to retry not just the failing builds, but any builds, including failed, cancelled, skipped or even successful builds (for example if last EWS run on a PR was many days back and you want to run EWS again). Please click on this button only when needed, as unnecessary retries might waste resources.
> If you are not listed in https://github.com/orgs/WebKit/teams/contributors/members and should have been listed there (e.g.: you are in contributors.json and have listed your GitHub account in it), please let me (or any WebKit admin) know.
