Auto recompiles the CSS doesn't work on DartSASS version 1.51.0

Hi, thanks for this library, it helps to integrate DartSASS to Phoenix much easy 💜

Issue

I'm noticed that the auto recompiles the CSS doesn't work on the DartSASS 1.51.0, it also happens on 1.50.0 and 1.50.1

That feature is working well on 1.49.11 FYI.

As I have checked on the DartSASS release changelogs, could it be related to sass/dart-sass#1411 🤔

Step to reproduce

1/ Generate a new Phoenix 1.6.x project
2/ Add DartSASS following the README
3/ Tested with the 1.49.11 version by adjusting the app.css, the new CSS should be written in priv folder and the browser is reloaded
4/ Change the version to 1.50.0 or 1.51.0, adjust the app.css the output CSS file in priv folder didn't update.

Hi @andyduong1920– unfortunately you are correct. There's a bug in 1.50+ that causes sass with --watch to exit immediately if opened by another program. I have an in-progress fix but it's not quite ready to merge. You can follow progress on the other PR:

• Ensure onStdinClose only completes for non-tty streams sass/dart-sass#1665

The vendor package has moved ahead several versions and we have updated our default version past the broken 1.50 release, so this should be less of an issue now :)
