add base64, logger and csv to Gemfile

Apparently, base64, logger and csv are "not part of the default gems starting from Ruby 3.5.0.

Thanks for your submission! Your observation is correct, but if you look closely at your screenshot you will see that the issue actually comes from the jekyll gem itself. They are the ones who have to add this gem to their gemspec. So this is a third-party issue.

Oh, you are right! I just removed base64, logger and csv and bumped the jekyll to the next (which is also the latest) minor version which also resolved the issue.

P.S. I specified "~> 4.4.0" instead of "~> 4.4.1" because they are equivalent since ~> treats the last number as a wildcard.
