Heex-file support seems not to be included in the 22.0.1 release

[michael-lemonbeat]

Describe the bug
Thank you very much for your tireless work on this plugin. I really appreciate your work and I can well imagine that you receive a lot of requests. Unfortunately, I have a question regarding release 22.0.1. It is suggested that this release includes support for Heex files (thanks to the amazing work from mwnciau (Simon James) (PR #3696), we now have HEEx support!), but I still see the open PR here #3696
And somehow, my setup (IntelliJ 2025.3 + plugin 22.0.1) does not recognize any Heex files as such. I assume that support will be added in the near future. Is my assumption correct?

To Reproduce
Steps to reproduce the behavior:
No file type "Heex" in the "file types" settings. All heex-files are shown as regular text files.

Expected behavior
Support of the heex-files.
