fix: package name in with-changesets release job (#9971)
### Description
Currently the release job points to the `docs` package. This is
incorrect as the package is actually called `@acme/docs` causing the
following error:
This pull request changes filter name to `@acme/docs` fixing the job.
This pull request also updates the documentation to reflect the actual
package name.
### Testing Instructions
Navigate to the `with-changesets` example and run `pnpm release`
