Unable to paginate releases in GitHub V3 API - github

Question

I'm trying to list all of the releases of a public repository on GitHub using their V3 API. Here's the request I'm making:
curl -is -H 'Accept: application/vnd.github.v3+json' \
https://api.github.com/repos/ffmpeg/ffmpeg/releases
The response headers I receive back are here:
HTTP/1.1 200 OK

Notice the lack of the Link response header? In the response body, I only get back around 7 releases and I can't seem to paginate forward or backward by manually specifying the ?page=N query parameter.
For some background, FFmpeg has about 226 releases present in its GitHub repository, and I'm only getting around 7 of those, unable to paginate through them.
Is there something I'm doing wrong here that would limit my responses back from the GitHub v3 API?

GitHub conflates its proprietary Releases feature with regular Git tags. Many of the "releases" that you see for ffmpeg are actually just tags.
Here is an example of a real release. Note how it contains much more information than a tag does. Despite their web UI showing tags mixed in with releases, GitHub's release API endpoint doesn't include regular tags:
This returns a list of releases, which does not include regular Git tags that have not been associated with a release. To get a list of Git tags, use the Repository Tags API.
Using the tags endpoint as GitHub suggests gives more results, and includes a Link header as you expect:
curl -is -H 'Accept: application/vnd.github.v3+json' \
