Rollup merge of #75211 - lzutao:native-endian-notes, r=lcnr

Note about endianness of returned value of {integer}::from_be_bytes and friends

[`u32::from_be`](https://doc.rust-lang.org/nightly/src/core/num/mod.rs.html#2883-2892) documents about endianness of returned value.

I was confused by endianness of `from_be_bytes` in #75086 .

 As the target platform's native endianness is used, portable code
 likely wants to use [`from_be_bytes`] or [`from_le_bytes`], as
