Raise minimum supported Swift version from 5.4 to 5.5 (#2267)
Motivation: SwiftNIO periodically drops support for older Swift versions. Now that 5.7 has been released, 5.4 will be dropped. Modifications: - Remove 5.4 specific Package.swift and docker-compose - Update the 5.7 docker-compose to use the released 5.7 and move from focal (2004) to jammy (2204) - Remove unused swiftformat from Dockerfile - Update tools version in syscall wrapper tests to 5.5 - Update docs Results: Minimum Swift version is 5.5

### SwiftNIO 2
|

|

This is the current version of SwiftNIO and will be supported for the foreseeable future.
|
||||
|
||||
The latest released SwiftNIO 2 version supports Swift 5.4+. NIO 2.29.0 and older support Swift 5.0+, NIO 2.39.0 and older support Swift 5.2+.
|

The most recent versions of SwiftNIO support Swift 5.5 and newer. The minimum Swift version supported by SwiftNIO releases are detailed below:

SwiftNIO | Minimum Swift Version

SwiftNIO 1 is considered end of life - it is strongly recommended that you move to a newer version. The Core NIO team does not actively work on this version. No new features will be added to this version but PRs which fix bugs or security vulnerabilities will be accepted until the end of May 2022.
