AWS linux documentation change
Summary
Updated formatting for Node.js EOL notice, fixed typo in reflink regression note, and added glibc tunable support for transparent huge pages with performance details.
Security assessment
Changes are documentation improvements and feature descriptions. The Node.js EOL notice is a routine maintenance warning, not a security vulnerability. The glibc update mentions performance optimizations without any security context.

This has been fixed in the current release. + + * With glibc version `glibc-2.34-231.amzn2023.0.3`, we bring support for enabling transparent huge pages via the glibc tunable framework from glibc v2.35 to AL2023. For some workloads, specifically those with a large memory working set and frequent random memory accesses, performance improvements of up to 10% can be achieved. This feature is not enabled by default because other workloads, such as some databases, see slowdowns when using it. The feature can be enabled by setting the environment variable `GLIBC_TUNABLES=glibc.malloc.hugetlb=1`.
