Upstream Catchup using github action

This wiki explains the process for the creation of upstream catchup PRs. We are using GitHub action Create Catchup PR. The action will be used in GitHub workflow which will be triggered weekly. The following steps will be performed every monday(let):

1. The action will be triggered on Monday at 12:00 AM (customizable).
2. A new branch will be created from RC:develop under the name develop_pwa-catchup-<latest sha from RC:develop>.
3. A Draft pull will be created from the new branch to develop_pwa.
4. After resolving conflicts(if any) and review, the PR will be ready to merge.
