[I] Removing a column from a `RecordBatch` drops schema metadata [arrow-rs]
kylebarron opened a new issue, #5327:
URL: https://github.com/apache/arrow-rs/issues/5327
**Describe the bug**
Calling `remove_column` on a `RecordBatch` object deletes any schema metadata.
In https://github.com/apache/arrow-rs/blob/a0148ba4cea1756bd22c534dff14e362cb5ee242/arrow-array/src/record_batch.rs#L357-L362
It creates the new `SchemaBuilder` exclusively from the fields which calls this `From impl`
https://github.com/apache/arrow-rs/blob/a0148ba4cea1756bd22c534dff14e362cb5ee242/arrow-schema/src/schema.rs#L125-L132
instead of also taking into account the schema metadata.
**To Reproduce**
I don't have a full repro example but can create one if needed.
