Suggestion: add slot list to API documentation

[datvm]

Description

Many elements like List or Text field has many slot names, sometimes with different names between components like icon vs trailing-icon. It would be nice to gather them all in one place like the Properties and Methods section of API.

Is it difficult to add? I assume you would need to add a JSDoc annotatation.

A welcome addition, but there isn't a jsdoc annotation to describe slot APIs, so we need to come up with our own and then implement it in our api analyzer scripts.

We can brainstorm suggestions here though!

Thanks for opening to the suggestion. Sorry I do not know how your analyzer script works or where it is. I think we can use something similar to @fire, like Tabs':

/**
 * @fires change {Event} Fired when the selected tab changes. The target's selected or
 * ...
 */
export class Tabs extends LitElement {

Maybe we can add something like this:

/**
 * @slots icon {Slot} Tabs may optionally show an icon.
 * Icons communicate the type of content within a tab.
 * Icons should be simple and recognizable.
 * ...
 */
export class Tab extends tabBaseClass {

Does this make sense? Is the analyzer script publicly available? I can try to take a look at it and see if I can help.

The scripts are located here https://github.com/material-components/material-web/tree/main/scripts/analyzer, and they use @lit-labs/analyzer.
