added ExtUtils::MakeMaker 7.64 to configure_requires

[rweikusat]

Added a configure_requires depenency on ExtUtils::MakeMaker 7.64 to META.json and META.yml so that perl Makefile.PL again works with Perl 5.30 because cpanm will now update MakeMaker if the version included with a particular perl version is too old.

@rweikusat Now all of the CI tests are failing, not just the Perl 5.36 ones, but I hope that's from the 2026 copyright thing?

If you look at the actual output, you'll see that the 5.30 tests now proceed to actually running tests instead of failing at the configuration stage and that the errors all come from the 99_lint.t copyright check. That's why I did the other pull request. I've created a makemaker-and-copyright branch in my forked repository with both changes and then, all tests pass.
