Schema class is missing in API docs

[mootari]

Describe the bug, including details regarding any error messages, version, and platform.

My understanding is that the Schema class is part of the public API, but it's not listed in the API docs (neither v20 nor v21). Other classes may be missing as well.

TypeDoc generates several warnings on build that may provide further insight: https://github.com/apache/arrow-js/actions/runs/15840019738/job/44650861254#step:5:324

Hmm. Could you take a look at this?
If we can fix this soon, we can include this in 21.0.0.

To be honest, I don't feel confident that I have the necessary background. I'm only familiar with Arrow and arrow-js at a very basic level, and the Git history for the TypeDoc configuration does not appear to provide context for how or why the current entrypoints and exclusions were chosen.

OK. Let's work on this after 21.0.0 release.
