JSDocs aren't being generated/published

In order to align with our other libraries, we should:

- Add `typedoc` as a dependency (use the same version as in the module template)
- Add a `build:docs` package script (refer to the module template)
- Add `publish-docs`, `publish-main-docs`, and `publish-rc-docs` GitHub workflows (see module template)

Review the module template first to identify the typedoc version, build:docs script, and workflow patterns to replicate. Then inspect the package configuration and existing GitHub workflows in detect-provider. Done means typedoc is declared, build:docs exists, and publish-docs, publish-main-docs, and publish-rc-docs workflows are added consistently.
