Swiftlint --fix adding weak to a non protocol value

[ppamorim]

New Issue Checklist

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

Similar to #3611 but #3599 won't fix.

Describe the bug

For the given variable:

private var fooDelegate: Bool = false

When running:

$ swiftlint --fix

Swiftlint is transforming var to weak var probably because it has delegate on the name, this is causing the compilation to fail.

I'm removing the rule here: #3809

It's extremely prone to false positives.
