explicit_type_interface collides with redundant_type_annotation for Bool

New Issue Checklist

• Updated SwiftLint to the latest version
• I searched for existing GitHub issues

Describe the bug

This bug exist in version 0.43 and is introduced by #3438

The above change re-introduced the bug #2312 for Bool as allow_redundancy is no longer honored.
The error doesn't repro in version older than 0.43

Complete output when running SwiftLint, including the stack trace and command used

$ swiftlint lint

Redundant Type Annotation Violation: Variables should not have redundant type annotation (redundant_type_annotation)

Environment

SwiftLint installed via brew

whitelist_rules:
  - redundant_type_annotation

  - explicit_type_interface

explicit_type_interface: # requires type annotation on everything but local variables and constants
  excluded:
    - local
  allow_redundancy: true # Ignores rule if it would result in redundancy
swiftlint_version: 0.43.1

To test execute

if which swiftlint >/dev/null; then
    swiftlint --config --strict .swiftlint.yml
else
    echo "warning: SwiftLint not installed, download from https://github.com/realm/SwiftLint"
fi

Xcode version 12.4

Swift code that triggers the warning

    private var isFirstLaunch: Bool = true

Start by reproducing the report with the shown .swiftlint.yml configuration, the swiftlint lint command, and the isFirstLaunch Swift snippet. Compare the explicit_type_interface and redundant_type_annotation behavior for Bool; done means allow_redundancy is honored and the redundant type annotation violation is no longer reported.
