Downgrades OpenSSL to 3.5.4

[bthomee]

High Level Overview of Change

This change downgrades OpenSSL 3.6.0 to 3.5.4.

Context of Change

To avoid potential zero-day issues in a new major version of OpenSSL, 3.6.0, it is safer to stick with 3.5.4. While 3.6.0 has some nice new features, such as improved SHA512 hashing, it also introduces new features that could contain bugs. In contrast, 3.5.4 has seen quite a few bug fixes over 3.5.0 and has been used in the wild for a while now.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Refactor (non-breaking change that only restructures code)
• Performance (increase or change in throughput and/or latency)
• Tests (you added tests for code that already exists, or your new feature included in this PR)
• Documentation update
• Chore (no impact to binary, e.g. .gitignore, formatting, dropping support for older tooling)
• Release
