[FEAT]: more than one file

[Pomax]

Describe the need

Right now if you want to use octokit to upload a bunch of text files, you either have to run one commit for each file using this plugin, or you need to play the insane "create blobs and paralllel paths, then a tree, then a commit, then update refs" REST API game. It would be so nice if this plugin had something normal for multiple text files as well as single text files, like

octokit.createOrUpdateTextFiles({ // note the plural
  owner,
  repo,
  branch,
  files: [ 
    { path: ... , content: ... },
    { path: ... , content: ... },
    { path: ... , content: ... },
  ]
);
