The entire match should be case-insensitive[1], so I'd add `i'
at the end:

	perl -pi -e 's|^Message-ID:\s*<?([^>]+)>?$|Link: https://lore.kernel.org/r/$1|gi;' "$1"

Fwiw, every mail and HTTP/1.x header parser I've looked at works
case-insensitively.  Also, I'm not sure if `g' is needed, actually...
