The URL generated for `releaseEvent` is invalid

[jamesgeorge007]

Currently, the URL generated for releaseEvent results in https://github.com/{release.name || release.tag_name}. Ref.

It should be handled explicitly as with the case of other events in the toUrlFormat method.

github-activity-readme/index.js

Lines 33 to 40 in 21d9a86

	const toUrlFormat = (item) => {
	if (typeof item === "object") {
	return Object.hasOwnProperty.call(item.payload, "issue")
	? `[#${item.payload.issue.number}](${urlPrefix}/${item.repo.name}/issues/${item.payload.issue.number})`
	: `[#${item.payload.pull_request.number}](${urlPrefix}/${item.repo.name}/pull/${item.payload.pull_request.number})`;
	}
	return `[${item}](${urlPrefix}/${item})`;
	};

if (Object.hasOwnProperty.call(item.payload, "release")) {
    return `[#${item.payload.release.tag_name || item.payload.release.tag_name}](${item.payload.release.html_url})`;
  }
