cmd/internal/obj/arm64: fix typos in document
The current document mismatches Go syntax loads a signed-byte
instruction "MOVB" with GNU syntax loads an 64bit double-word
instruction "ldr". This is just a typo in the document, the
assembler has the correct encoding. This patch fix this error.
Fixes #39367
