docs: recommend musl and 128 GB swap for validators

[kp2pml30]

Recommend musl libc on Linux and document GenVM's default ELF interpreter paths for AMD64 and AArch64, preserving the current AMD64-only validator support statement

Recommend 128 GB of swap as a conservative starting point while transaction throughput and memory demand are unknown. Keep the existing 128 GB disk recommendation and clarify that it excludes swap. Update both the requirements page and setup summary

Validation

• Both changed pages compile with Nextra
• The musl section link resolves to the generated heading anchor
• Independent review found no issues; the final disk wording was recompiled after review
• git diff --check passed

Documentation only; no full site build or E2E requested
