chore: update kernel and microcode

This should provide software mitigations for the below when microcode
patches are not yet available:

- https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/technical-documentation/gather-data-sampling.html
- https://www.amd.com/en/resources/product-security/bulletin/amd-sb-7005.html

The linux-microcode update should have microcode fixes for ZenBleed.
