fix GNU-only \+ in check-pins sed patterns

Browse Source 
\+ is a GNU BRE extension; /usr/bin/sed on macOS treats it as a literal
plus, so every Dockerfile ARG pin was reported "not found" and make
check false-failed even though mise.toml and the Dockerfile agree. Use
the POSIX form \{1,\} and note the constraint in the header.
