textSerializers in getText don't override renderText set in schema

[harrisonlo]

What’s the bug you are facing?

Similar to #3538, the getText utility needs to have these 2 lines updated:

return getText(this.state.doc, {
    blockSeparator,
    textSerializers: {
      ...getTextSerializersFromSchema(this.schema),
      ...textSerializers
    }
})

Which browser was this experienced in? Are any special extensions installed?

Chrome, no special extensions.

How can we reproduce the bug on our side?

Using the example in #3538, simply replace the generateText usage with editor.getText().

Can you provide a CodeSandbox?

No response

What did you expect to happen?
