Account for replication delay after repository was created

[gr2m]

We currently add the octoherd-script topic right after we create the repository

create-octoherd-script/lib/create-repository.js

Lines 16 to 34 in 1831fd1

	let repositoryResponse;
	if (isUserRepo) {
	repositoryResponse = octokit.request("POST /user/repos", createRepoOptions);
	} else {
	repositoryResponse = octokit.request("POST /orgs/{org}/repos", {
	org: owner,
	...createRepoOptions,
	});
	}
	// add topic
	await octokit.request("PUT /repos/{owner}/{repo}/topics", {
	mediaType: {
	previews: ["mercy"],
	},
	owner,
	repo,
	names: ["octoherd-script"],
	});

That can result in a 404 due to the replication lag in GitHub's databases.

We should add an explicit retry to the request which adds the topic. For that we need to use Octokit's retry plugin, then we need to add { request: { retries: 3, retryAfter: 1 } } to the request options. The replication lag should never be longer than 3 seconds.

As we need the retry plugin, we could as well replace @octokit/core with @octoherd/octokit which already has the retry request loaded.
