Fixes #10625 and reverts part of #10577.

Only the Ruby version (2.5) to runtime should have been dropped, not code analysis.
This PR the specification to TargetRubyVersion: 2.5 So, this keeps it compatible with TargetRubyVersion up to 1.28.2.


Before submitting the PR make sure the following are checked:

  • The PR relates to only one subject with a clear title and description in grammatically correct, complete sentences.
  • Wrote good commit messages.
  • Commit message starts with [Fix #issue-number] (if the related issue exists).
  • Feature branch is up-to-date with master (if not - rebase it).
  • Squashed related commits together.
  • Added tests.
  • Ran bundle exec rake default. It executes all tests and runs RuboCop on its own code.
  • Added an entry (file) to the changelog folder named {change_type}_{change_description}.md if the new code introduces user-observable changes. See changelog entry format for details.

This PR fixes default Ruby version from 2.5 to 2.6.

In rubocop#10626 (RuboCop 1.29.1) , the default target Ruby version is 2.5. This is an unexpected
regression behavior and the default target Ruby version is expected to be 2.6.

…ersion: 2.4`

Fixes rubocop#10258 and reverts part of rubocop#9648.

Only the Ruby version (2.4) to runtime should have been dropped,
not code analysis.
This PR makes Ruby 2.4 code analysis with `TargetRubyVersion: 2.4`.
So, this keeps it compatible with `TargetRubyVersion` up to
RuboCop 1.12.1 as semver.

It aims to solve essentially the same problem as rubocop#10626.

RuboCop can analyze Ruby 1.9 or later. But now it turns out that RuboCop
hasn't been able to parse older Ruby versions.
https://docs.rubocop.org/rubocop/1.29/compatibility.html#support-matrix

Analysis Ruby code and runtime Ruby versions are different.
So, only runtime version should have been dropped.

This PR makes it possible to parse older Ruby versions that were
accidentally dropped before RuboCop AST was separated from RuboCop core.

With this fix, the following recovery work will be possible.

- Recover for Ruby 2.5 analysis: rubocop/rubocop#10626
- Recover for Ruby 2.4 analysis: rubocop/rubocop#10632

Reverts part of rubocop#7869 and rubocop#8056.

Only the Ruby version (2.3) to runtime should have been dropped, not
code analysis.
This PR makes Ruby 2.3 code analysis with `TargetRubyVersion: 2.3`.
It aims to solve essentially the same problem as rubocop#10626 and 10632.

And this change requires RuboCop AST 1.18 or later:

Reverts part of rubocop#6766, rubocop#7026, and rubocop#7030.

Only the Ruby version (2.2) to runtime should have been dropped, not code analysis.
This PR makes Ruby 2.2 code analysis with `TargetRubyVersion: 2.2`.
It aims to solve essentially the same problem as rubocop#10626, rubocop#10632, and rubocop#10640.

Previously, there was the following default enforced style `when_needed` for
`Style/FrozenStringLiteralComment` cop.

```ruby
# @example EnforcedStyle: when_needed (default)
#   # The `when_needed` style will add the frozen string literal
#   # to files only when the `TargetRubyVersion` is set to 2.3+.
#   # bad
#   module Foo
#     # ...
#   end
#
#   # good
#   # frozen_string_literal: true
#
#   module Foo
#     # ...
#   end
```

This PR does not restore that option, but sets the `minimum_target_ruby_version 2.3`
to make `always (default)` apply by default. It is a simple solution that does not
handle frozen literal magic comment added in Ruby 2.3 when `TargetRubyVersion` is
Ruby 2.2 or lower.
