docs(scripts): update auto install desc

 - The dependencies of source code compilation are placed in the `mmdeploy-dep` directory at the same level as mmdeploy
 - The script would not modify variables such as PATH, LD_LIBRARY_PATH, PYTHONPATH, etc.
+- The environment variables that need to be modified will be printed, **please pay attention to the final output**

+The script will eventually execute `python3 tools/check_env.py`, the successful installation should display the version number of the corresponding backend and `ops_is_available: True`, for example:

 Here is the verified installation script. If you want mmdeploy to support multiple backends at the same time, you can execute each script once:
