Add ability to include additional files

[mheap]

Include files other than main when creating a commit to update a tag. This will not be needed by most people, but is required if you're bundling ncc using ncc due to Error: ENOENT: no such file or directory, open '/home/runner/work/_actions/owner/repo/v1/dist/index.js.cache.js'

Just saw this and I would need the same functionality to include a license file with the releases.

@JasonEtco could you please consider this for merging?

I'd really like to have this feature! Instead of an input option, how about just including the files matched in the "files" entry in package.json?

Example:

{
  "name": "your-action-name",
  "main": "dist/index.js",
  "files": [
    "dist/licenses.txt"
  ],
  "scripts": {
    "build": "npx @vercel/ncc build && npx convert-action"
  }
}

@JasonEtco any chance you might want to integrate this or #24?

I would really like to include the README into the release tag (so that viewing older releases on the marketplace also shows the readme).

See for example an older version of this action itself:

Any updates over here ?

I'd really like this too. Love the workflow of this action but need to include a wasm file along side the ncc generated index.js. @JasonEtco?

@mheap turns out there's a bug in the PR (technically a bug exposed by this PR as it enables deployment of binaries). I forked into our org and used it to deploy a wasm with an action (as mentioned before) but discovered that the binary was corrupted by the roundtrip through utf-8. See https://github.com/primait/build-and-tag-action/commit/183ecd810e27f87e8265b87b40bafd45b977c6a4

@EddieWhi Excellent catch! I've cherry picked in to this PR in case it helps anyone else
