avoid using stt-align-node!

[Niceblueman]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch slate-transcript-editor@0.1.6-alpha.19 for the project I'm working on.

Here is the diff that solved my problem:

diff --git a/node_modules/slate-transcript-editor/util/export-adapters/slate-to-dpe/update-timestamps/plain-text-align-to-slate.js b/node_modules/slate-transcript-editor/util/export-adapters/slate-to-dpe/update-timestamps/plain-text-align-to-slate.js
