Compatibility of nginx for the module

Hi Folks,
I wanted to know what are the ranges of (minimum and maximum) version of nginx on which this module is supported?
```[tasklist]
### Tasks
```

The issue names no files, tests, or entry points. First investigate the module's nginx compatibility from its build requirements and available project history, then document the minimum and maximum supported nginx versions. Done means the supported range is established and recorded in the appropriate project documentation.
