fix: disable wasm highlighter for big endian platforms

[kxxt]

Description

In PR fix: disable wasm highlighter on riscv64, as an unrelated change, the wasm highlighter is re-enabled for s390x given the corresponding bug has been fixed. It later broke node.js CI in nodejs/node#62512 because the wasm highlighter is not compatible with big endian platforms like s390x.

Thus disable the wasm highlighter for all big endian platforms until it is fixed.

PR Summary

Low Risk
Low risk: a small runtime guard changes when the WASM highlighter is enabled, primarily affecting syntax highlighting performance/compatibility on big-endian architectures.

Overview
Disables the WASM-backed Shiki highlighter on all big-endian platforms by gating wasm behind endianness() === 'LE' (while keeping the existing riscv64 restriction).

Bumps the package version from 1.3.3 to 1.3.4 (including the lockfile) to ship the fix.

@nodejs/web-infra I believe this needs to be fast-tracked as hot-fix, @kxxt last favor, could you please bump the version of doc-kit on the package.json?

Done. Sorry about the delay. I was away from my computer for a while.
