Release 0.15.1

[johnnagro]

Bumps the version to 0.15.1 and adds the changelog entry.

Changes since 0.15.0

• Fully suppress Rails' default Action View logs on Rails 7.1+ by also removing ActionView::LogSubscriber::Start (Unsubscribe all Rails built-in subscribers #386, fixes ActionView logs not completely suppressed with Rails 7.1+ #385)
• Declare logger as a runtime dependency in the gemspec, since it is no longer a default gem in newer Rubies (Add 'logger' as dependency in gemspec #401)

CI and tooling fixes from #405 are also included but don't affect the released gem.

Verified locally (Ruby 3.4.10)

• Specs pass on Rails 6.1, 7.0, 7.1, 7.2, 8.0, 8.1 and the default Gemfile
• RuboCop clean
• gem build produces lograge-0.15.1.gem containing only lib/ and LICENSE.txt, with logger listed as a runtime dependency
