Release 1.5.1

Various housekeeping activities: - Added dependabot management for actions and gems. We may not keep the gems until Diff::LCS v2 is released and only Ruby 3.0 or higher are supported. - Tweaked CI configuration to remove unsupported macOS versions and add `standardb` checks to the build for Ruby 3.3. - Fixed CodeQL. - Performed long-overdue maintenance on the History and Contributing files. - Updated the gem SPDX identifier for GPL 2.0 or later, resolving #86 by Vit Ondruch. - Resolve a potential security issue with `ldiff` in its use of `IO.read` instead of `File.read`. [#91][] - Added MFA authentication requirement for release to RubyGems. Resolves: #86 Resolves: #91
