Auto merge of #28389 - aidanhs:aphs-update-musl-linking, r=steveklabnik

In addition to instruction updates I
 - changed from wget to curl, because curl is a prerequisite of rust itself
 - removed `[...]` because they're missing from so many places it would just obscure the instructions if they were all put in

r? @steveklabnik
