add hack/sync-enhancements-github-project-beta.sh

[Priyankasaggu11929]

What type of PR is this:

/kind feature

What this PR does / why we need it:

The PR adds a script called hack/sync-enhancements-github-project-beta.sh.

This script will be run as part of a periodic Prow Job that will sync all open KEP issues from the k/enhancements repository under a current release milestone (say v1.25) to an Enhancements GitHub Project Beta board (similar to https://github.com/orgs/kubernetes/projects/87).

Limitations/assumptions:

As of the time of writing, there is no GitHub project beta api endpoint available for ~creating a project~[1] (and its columns and views) using github cli (gh). Only existing project field mutations are possible. Hence the following assumptions are made:

• The script expects that a GitHub Project Beta board has previously been created with at least the column fields (Issue Number & KEP) existing under the kubernetes organisation.
• The script expects receiving the above project number from the environment variable GITHUB_PROJECT_BETA NUMBER.

Update (July 22, 2022 [1] api for creating v2 project: mutations#createprojectv2

FYI: The GitHub Project Beta board does not currently allow cloning/duplicating an existing project, which might be a blocker cc: @mrbobbytables

The plan is, with each new release cycle, the lead simply clone/duplicate the previous release cycle's project board and update the periodic Prow Job with the cloned new Project number and the then current "release milestone".

Without the option to clone/duplicate a project, each release cycle requires manually creating the project and adding all columns (respective data validations) and different views, which takes quite a lot of time.

Open to discussion, if we can come up some better approach. Thank you!

IMO - I don't think its a blocker, its a bit of administrative overhead, yes but not massive. We may wind up iterating on how the boards are used as more functionality is added as well.

Also a side note while testing, I was prompted to login via gh auth login or adding Github token. The first option doesn't work because I can't authorize for project using it so you gotta add the environment variable.

@gracenng @marosset I have reworked the script to filter k/enhancements issue by the label "lead-opted-in".

(Have tested it here https://github.com/orgs/kubernetes/projects/87/views/1)

PTAL. Thank you!

Once this script is merged, will do a quick revamp of the https://github.com/kubernetes/test-infra/pull/26812 to have the periodic script run in place.

@mrbobbytables appreciate if we can merge the PR to help the release team automate the Enhancement GH project :)
