URL: https://github.com/apache/arrow/issues/54689
### Describe the bug, including details regarding any error messages,
version, and platform.
A stream exported from an Arrow::TableBatchReader crashes when it is
imported, if the table it was created from has been garbage collected.
```
require "arrow"
address = Arrow::TableBatchReader.new(Arrow::Table.new("a" =>
Arrow::Int32Array.new([1, 2, 3]))).export
GC.start
p Arrow::RecordBatchReader.import(address).read_all
# => [BUG] Segmentation fault at 0x0000000000000018
```
The crash is in arrow::ExportSchema, called from ExportStreamSchema:
```
libarrow.2500.1.0.dylib(_ZN5arrow12ExportSchemaERKNS_6SchemaEP11ArrowSchema+0x90)
libarrow.2500.1.0.dylib(_ZN5arrow12_GLOBAL__N_118ExportStreamSchemaERKNSt3__110shared_ptrINS_17RecordBatchReaderEEEP11ArrowSchema)
```
Environment: red-arrow 25.0.1, apache-arrow-glib 25.0.1 (Homebrew), Ruby
3.4.1, macOS 15.4.1 (arm64)
