[feat] Native Support for .njk Files in Beautify #2127
Description
Describe the problem
Currently, the Beautify feature doesn't support the .njk file type out-of-the-box. Since Nunchucks (.njk) has its own templating syntax with directives like {{ }} and {% %}, it isn't recognized as standard HTML.
Current behavior:
Editing .njk files shows the Beautify option as greyed out/disabled.
Applying an HTML language override does not enable Beautify for these files.
Describe the solution you'd like
Enable the Beautify feature for .njk files by recognizing Nunchucks templating syntax.
