This version of Splash includes support for highlighting code written using Swift 5.5's new concurrency features, including async/await and actor types. It also upgrades the Swift version that Slash uses to 5.4.

Syntax highlighting has also been corrected in the following situations:

• When nil is used within a ternary operation.
• When a comment is placed next to an array type or literal.
• When an underscore is used to ignore function parameters.
• When a property wrapper's projected value is used.

This release also includes documentation fixes by @Yaacoub and @haikusw, and an infrastructure improvement by @fjcaetano.
