GH-48287: [Ruby] Add minimum pure Ruby Apache Arrow reader implementation (#48288)

### Rationale for this change

We want to implement step by step. Let's add only minimum implementation and base configuration as the first step. This doesn't have full reader implementation.

### What changes are included in this PR?

This includes the followings:

* Prepare package
  * We use red-arrow-format as package ID
  * We use Red Arrow Format as package name
* Auto generated FlatBuffers code
  * It's generated by red-flatbuffers
* Add minimum file format reader
  * It can read only UInt8 array
* CI configuration

### Are these changes tested?

Yes.

### Are there any user-facing changes?

Yes.
* GitHub Issue: #48287
