Node.js v23.8.0 introduced official Zstandard (zstd) support on node:zlib module: https://nodejs.org/en/blog/release/v23.8.0#support-for-the-zstd-compression-algorithm

Zstandard provides numerous benefits compared to older alternatives and considering Axios supports compression algorithms included in the zlib module, it makes sense to include zstd too.

Describe the solution you'd like

Support zstd in a same manner to Brotli and gzip.

Describe alternatives you've considered

• Handle compression in application by combining responseType: 'arraybuffer' and decompress: false options: the application can no longer benefit from integrated decompresion provided by Axios.
