Update zeitwerk requirement from ~> 2.6.6 to >= 2.6.6, < 2.8.0

[dependabot]

Updates the requirements on zeitwerk to permit the latest version.

Changelog

Sourced from zeitwerk's changelog.

2.7.1 (19 October 2024)

• Micro-optimization in a hot path.

• Raises Zeitwerk::Error if an autoloaded constant expected to represent a namespace does not store a class or module object.

• Adds truffleruby-head to CI, except for autoloading thread-safety (see why in oracle/truffleruby#2431).

2.7.0 (11 October 2024)

• Explicit namespaces can now also be defined using constant assignments.

  While constant assignments like

  # coordinates.rb
  Coordinates = Data.define(:x, :y)

  worked for most objects, they did not for classes and modules that were also namespaces (i.e., those defined by a file and matching subdirectories). In such cases, their child constants could not be autoloaded.

  This limitation has been removed.

• TracePoint is no longer used.

• Requires Ruby 3.2 or later.

  Gems that work with previous versions of Zeitwerk also work with this one. If they support Ruby versions older than 3.2 they can specify a relaxed version constraint for Zeitwerk like "~> 2.6", for example.

  In client projects, Bundler takes the Ruby requirement into account when resolving dependencies, so Gemfile.lock will get one compatible with the Ruby version being used.

2.6.18 (2 September 2024)

• Fixes a bug in which projects reopening the main namespace of a gem dependency managed by its own Zeitwerk loader could not reload the constants they added to that external namespace.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
