GH-48610: [Ruby] Add FixedSizeListArray glue (#48609)
### Rationale for this change
When testing ListSliceOptions I noticed that some glue were missing from
the Ruby code.
### What changes are included in this PR?
This adds the `FixedSizeListArrayBuilder.build` method in Ruby.
### Are these changes tested?
Yes.
### Are there any user-facing changes?
This makes it easier to create `FixedSizeListArray` objects in Ruby.
