GH#52024 [Python] Fix show_info() codec list

[Asthenia0412]

Background

In show_info(), the codec list had both lz4_frame and lz4 which both map to the same compression type (CCompressionType_LZ4_FRAME), while the independent lz4_raw (CCompressionType_LZ4) was missing.

Problem

Users running pa.show_info() saw one codec listed twice and could not see that lz4_raw was available.

Solution

Changed the codec list from ["brotli", "bz2", "gzip", "lz4_frame", "lz4", "snappy", "zstd"] to ["brotli", "bz2", "gzip", "lz4_frame", "lz4_raw", "snappy", "zstd"].

Testing

Verified that the new list no longer duplicates any codec and now includes the distinct lz4_raw.
