update zlib to 1.2.13 with:

Version 1.2.13 has these key updates from 1.2.12:

- Fix a bug when getting a gzip header extra field with inflateGetHeader(). This remedies CVE-2022-37434.
- Fix a bug in block type selection when Z_FIXED used. Now the smallest block type is selected, for better compression.
- Fix a configure issue that discarded the provided CC definition.
- Correct incorrect inputs provided to the CRC functions. This mitigates a bug in Java.
- Repair prototypes and exporting of the new CRC functions.
- Fix inflateBack to detect invalid input with distances too far.
