licenses.txt no longer part of dist/

[Skenvy]

It would appear that the generated dist folder doesn't contain a licenses.txt file like it used to, to aggregate all the licenses of the modules used to bundle the dist.

I noticed this because the last time I used this was back in May last year which included this --license licenses.txt option

typescript-action/package.json

Line 33 in c55649f

"package": "npx ncc build src/index.ts -o dist --source-map --license licenses.txt",

I can't see any specific mention in #969 about the intentionality of removing the license or any other issues regarding it besides #957, so wondering if it'd be good to suggest adding something like https://www.npmjs.com/package/rollup-plugin-license to this.
