How to document optional or "available" plugins?

[michaelborn]

So EmojiLog support adds two additional plugins:

• EmojiLogCommitParser
• EmojiLogCommitAnalyzer

I'd like to add docs for these to the README, but the current ### Plugins: description does not apply to "optional" plugins:

Plugins:

The following plugins are used in CommandBox Semantic Release. They are ran in
the order they are presented...

How can we change the README docs from "these plugins run in X order" to "the following plugins are available:"?

What if we change the table from a list of plugins which implement XYZ interface to a table of interfaces, with supported implementations?

Interface	Purpose	Default	Options
CommitAnalyzer	Analyzes the commits to determine the release type.	DefaultCommitAnalyzer	DefaultCommitAnalyzer, EmojiLogCommitAnalyzer
