fix!: Change copilot_code_review field names to match GitHub API

[JiayangZhou]

BREAKING CHANGE: CopilotCodeReviewRuleParameters.ReviewNewPushes is now ReviewOnPush.

Rename ReviewNewPushes to ReviewOnPush with json tag review_on_push

Hey sorry when I reviewed the github API doc https://docs.github.com/en/rest/repos/rules?apiVersion=2022-11-28 I noticed that the payload parameter we previously used was incorrect, thus I am creating this PR to correct it, sorry for the innocence!

Edit: also added MarshalJSON tests under func TestRepositoryRule. currently only for copilot_code_review 'creation' i guess others can add if they want

Edit2:
I think you are right from the beginning, i was too naive, so for this API

go-github/github/repos_rules.go

Line 41 in 1830689

func (s *RepositoriesService) GetRulesForBranch(ctx context.Context, owner, repo, branch string, opts *ListOptions) (*BranchRules, *Response, error) {

the respond body is Unmarshaling to BranchRules and it does include codepilot,
i verified it from here too https://docs.github.com/en/rest/repos/rules?apiVersion=2022-11-28#get-rules-for-a-branch

I noticed that the payload parameter we previously used was incorrect

@JiayangZhou It is not your fault. GitHub just changed payload params for Copilot Code Review to move it from Pull Request property boolean to Rules root object without bumping API version last week. We encountered same issue. And since this field was in Preview, they didn't even bother to announce breaking change API.

It's a good job they added API versioning... 👀
