Subject: [PATCH] fix(cmake): Replace deprecated FetchContent_Populate with
 FetchContent_MakeAvailable

Update `source/lmp/plugin/CMakeLists.txt` to use `FetchContent_MakeAvailable` instead of `FetchContent_Populate`.

* Replace `FetchContent_Populate(lammps_download)` with `FetchContent_MakeAvailable(lammps_download)` on line 13.
* Remove `FetchContent_GetProperties` and `if(NOT lammps_download_POPULATED)` block.

This fixes a CMake warning:
```
CMake Warning (dev) at /home/runner/work/_temp/-111029589/cmake-3.30.5-linux-x86_64/share/cmake-3.30/Modules/FetchContent.cmake:1953 (message):
  Calling FetchContent_Populate(lammps_download) is deprecated, call
  FetchContent_MakeAvailable(lammps_download) instead.  Policy CMP0169 can be
  set to OLD to allow FetchContent_Populate(lammps_download) to be called
  directly for now, but the ability to call it with declared details will be
  removed completely in a future version.
Call Stack (most recent call first):
  lmp/plugin/CMakeLists.txt:13 (FetchContent_Populate)
This warning is for project developers.  Use -Wno-dev to suppress it.
```
