docs: Add docs publish workflow

[crandmck]

Add a worfkow to publish doc on each release.

• Remove the generated .md doc files from the repo.
• Add workflow to automatically rebuild the docs on each release

Note: This will require keeping the handful of existing Jekyll scaffolding files which in general won't need to change.

I believe this will replace #29

What's happening here exactly - do we build the docs and then remove the directory?

[crandmck]

This deletes the md files that typedoc generates in the docs-typedoc directory. Jekyll then processes these into HTML files, which are what GHP serves.

However, I notice that the build:docs script in package.json already does this--twice actually (added newlines for readability):

"build:docs": "rimraf docs-typedoc && 
typedoc --plugin typedoc-plugin-markdown --readme README.md --out docs-typedoc js-src/index.ts && 
cpy \"docs-typedoc/**\" docs --parents --overwrite --ignore=\"docs-typedoc/classes/index.md\" --ignore=\"docs-typedoc/README.md\" && 
rimraf docs-typedoc",

Not sure why there are two rimraf docs-typedoc commands there...
But I think we could probably remove all but one of these. Is it better to do it in the workflow or in the pnpm script?

[emensch]

I would do as much in the workflow as is possible.

Question - is it necessary to do an intermediate markdown step?

I only ask because we don't bother with that in the web SDK. We just build directly to HTML and push that to GHP: https://github.com/contentauth/c2pa-js/blob/main/.github/workflows/publish-docs.yml#L38-L44
