if let - guard let shorthand misusage

[wynioux]

A short summary of issue: In our guideline there is a misuse of optional binding using if let foo = foo { ... } and guard let foo = foo else { ... }.

Reasoning and motivation: After release of Swift 5.7 we can use new if let foo { ... } and guard let foo else { ... } shorthand syntax as our guideline mentioned here.
