Condense list of "available when" constraints

[dimitribouniol]

Description

When a type has a complex set of generics and constraints on those generics, a single relevant constraint on a method can really be lost in the generated documentation. For instance, in the example below, the only meaningful constraint for this method is in the extension's where clause: AccessMode == ReadWrite. However, the documentation insists on expanding the main type's constraints as well:

public actor Datastore<
    Version: RawRepresentable & Hashable & CaseIterable,
    CodedType: Codable,
    IdentifierType: Indexable,
    AccessMode: _AccessMode
> where Version.RawValue: Indexable & Comparable { ...

Checklist

• If possible, I've reproduced the issue using the main branch of this package.
• This issue hasn't been addressed in an existing GitHub issue.

Expected Behavior

"Available when" lists only AccessMode == ReadWrite.

Actual behavior

"Available when" lists the constraints of the entire type, which should have already been met by the time the user calls this method being documented. If the constraints need to me mentioned (in the case of a static method, for instance, as they inform the resulting type), they should at least be in a more consumable format, perhaps a bulleted list, or in a more concise blurb listing easy "source" type once?

ie. instead of:

Available when Version conforms to CaseIterable, Version conforms to Hashable, Version conforms to RawRepresentable, CodedType conforms to Decodable, CodedType conforms to Encodable, IdentifierType conforms to Comparable, IdentifierType conforms to Decodable, IdentifierType conforms to Encodable, AccessMode is ReadWrite, Version.RawValue conforms to Comparable, Version.RawValue conforms to Decodable, and Version.RawValue conforms to Encodable.

show:

Available when Version conforms to CaseIterable, Hashable, and RawRepresentable; CodedType conforms to Decodable, and Encodable; IdentifierType conforms to Comparable, Decodable, and Encodable; AccessMode is ReadWrite; and Version.RawValue conforms to Comparable, Decodable, and Encodable.

Better, list these in alphabetical order?

Available when AccessMode is ReadWrite; CodedType conforms to Decodable, and Encodable; IdentifierType conforms to Comparable, Decodable, and Encodable; Version conforms to CaseIterable, Hashable, and RawRepresentable; and Version.RawValue conforms to Comparable, Decodable, and Encodable.
