Germán Jabloñski c701dd41a9 docs: update rich text to HTML conversion documentation (#12465)
Fixes #8168, #8277

The fact that `lexicalHTMLField` doesn't work with live preview was
already clarified at the beginning of the page. I mentioned it again in
the dedicated section because it seems there was still confusion.

Also, I reordered and hierarchized the headings correctly. The
introduction said there were two ways to convert to HTML, but there were
four headings with the same level. I also made the headings a little
shorter to make the table of contents easier to parse.

## Richtext to Plaintext
Here's how you can convert richtext data to plaintext using `@payloadcms/richtext-lexical/plaintext`.
```ts
import type { SerializedEditorState } from '@payloadcms/richtext-lexical/lexical'
import { convertLexicalToPlaintext } from '@payloadcms/richtext-lexical/plaintext'
// Your richtext data here
const data: SerializedEditorState = {}
const plaintext = convertLexicalToPlaintext({ data })
```
### Custom Converters
The `convertLexicalToPlaintext` functions accepts a `converters` object that allows you to customize how specific nodes are converted to plaintext.
```ts
import type {
DefaultNodeTypes,
SerializedBlockNode,
} from '@payloadcms/richtext-lexical'
import type { SerializedEditorState } from '@payloadcms/richtext-lexical/lexical'
import type { MyTextBlock } from '@/payload-types'
import {
convertLexicalToPlaintext,
type PlaintextConverters,
} from '@payloadcms/richtext-lexical/plaintext'
// Your richtext data here
const data: SerializedEditorState = {}
const converters: PlaintextConverters<
DefaultNodeTypes | SerializedBlockNode<MyTextBlock>
> = {
blocks: {
textBlock: ({ node }) => {
return node.fields.text ?? ''
},
},
link: ({ node }) => {
return node.fields.url ?? ''
},
}
const plaintext = convertLexicalToPlaintext({
converters,
data,
})
```
Unlike other converters, there are no default converters for plaintext.
If a node does not have a converter defined, the following heuristics are used to convert it to plaintext:
- If the node has a `text` field, it will be used as the plaintext.
- If the node has a `children` field, the children will be recursively converted to plaintext.
- If the node has neither, it will be ignored.
- Paragraph, text and tab nodes insert newline / tab characters.
