* @example
* #### Find and replace text in a file hosted on a GitHub repository
* ```typescript
* const octokit = new Octokit({ auth: "your-github-token" });
* await findAndReplaceInGithubFile({
* octokit,
* owner: "username",
* repo: "repository",
* path: "path/to/file.txt",
* regex: /findMe/g,
* replacement: "replaceWithMe",
* commitMessage: "Replaced 'findMe' with 'replaceWithMe'"
