IndentFeature causes pressing Tab in the middle of a block such as a
paragraph or heading to insert a TabNode. This property allows you to
disable this behavior, and indentation will occur instead if the block
allows it.
Usage:
```ts
editor: lexicalEditor({
features: ({ defaultFeatures }) => [
...defaultFeatures,
IndentFeature({
disableTabNode: true,
}),
],
}),
```
