AWSVerifiedPermissions service fails to compile

[jbelkins]

Describe the bug

The AWSVerifiedPermissions service, which was introduced after AWS SDK release 0.18.0, includes a struct property named set. set is also a reserved word in Swift.

The serialization extension for that struct tries to escape `set` in backticks, then combine it with the suffix Container, which results in an invalid Swift identifier and a compile error.

/Users/runner/work/aws-sdk-swift/aws-sdk-swift/Sources/Services/AWSVerifiedPermissions/models/Models.swift:136:18: error: found an unexpected second identifier in constant declaration; is there an accidental break?
        let `set`Container = try values.decodeIfPresent([VerifiedPermissionsClientTypes.AttributeValue?].self, forKey: .`set`)
                 ^

Expected Behavior

Swift compiles correctly.

(More specifically, the generated Swift identifier should be setContainer with nothing backticked.)

Current Behavior

Swift compiles with the error identified above.

Reproduction Steps

Generate Swift code from latest models
Compile SDK including the AWSVerifiedPermissions service.

Possible Solution

Fix generation of symbols from Swift reserved words.
